Four 12-year-old girls grow up together during an eventful small-town summer in 1970.

Scott: Roberta?
Roberta: What?
Scott: Why do you think we fight all the time?
Roberta: Just something to do, I guess. Why?
Scott: 'Cause... 'cause I think you are a real nice girl.
Roberta: I always thought you hated me.
Scott: So did I...
Scott: Uh, Roberta, canIkissyou?
Roberta: What are you mumbling?
Scott: Uh, would it be all right... can I kiss you?
Teeny: Chrissy, truth or dare?
Chrissy: Truth.
Teeny: Have you ever been french kissed?
Chrissy: Are you kidding? I don't want to get pregnant!
[Roberta gets up, slams the record player shut and starts pacing back in forth in anger]
Chrissy: Roberta it's ok
Roberta: NO IT'S NOT OK! It's not OK! Why did they have to die? Why did SHE have to die? My dad lied to me he said that this BEAUTIFUL angel swooped down to earth and he carried her away... BEFORE SHE HAD A SECOND TO FEEL ANY PAIN! Why did she have to die? Why did he have to lie to me? He's all I have left and he lied...
Samantha: As we grow older, it becomes difficult to just believe. It's not that we don't want to, but too much has happened and we can't.
Young Samantha Albertson: [walking to Dear Johnny's grave to lay flowers and sees Crazy Pete putting flowers on Johnny and his mothers grave] You're Peter Sims
Crazy Pete: [nods in agreement, turns to face the headstones] They were my family...
Young Samantha Albertson: It was a terrible thing that happened to them... I'm sorry...
Crazy Pete: For the longest time I thought I could've stopped it... I would've been home... Instead of down at that bar...
Young Samantha Albertson: But you were there for me...
Crazy Pete: I've wasted a lot of years... Afraid to face people, but mostly afraid to face myself...
Young Samantha Albertson: [takes Pete's hand] I'm scared too...
Crazy Pete: [smiles] What's you're name?
Young Samantha Albertson: Samantha...
Crazy Pete: Well Samantha... Things will happen in your life that you can't stop... But that's no reason to shut out the world... There's a purpose for the good and for the bad...
Samantha: [Older Samantha's voice narrating] He gave me the only gift he could... The lesson that had taken him a lifetime to learn... And although I understood the importance of his words... It's only now looking back that I understand their meaning
Crazy Pete: I don't want to see a lot of people, I don't think they want to see a lot of me.
Chrissy: It makes me look fat.
Teeny: You ARE fat.
Chrissy: I am NOT fat! Am I fat?
Roberta: I think you'll make a great mum Chrissy, a little overbearing and rigid, but by the grace of God the kid will come out relativity unharmed, if not there's always therapy.
Samantha: This whole baby thing baffles me, I mean you have it, you raise it, you inevitably screw it up, it resents you, feels guilty for resenting you and then it has a baby, which only perpetuates the vicious cycle.
Roberta: Thank you, Oscar The Grouch.
Roberta: Scott?
Scott: Yeah?
Roberta: If you tell anyone about this, especially your brothers, I'll beat the shit out of you.
Roberta: ...Perky breasts!
Chrissy: Roberta, you know I don't like it when you swear.
Roberta: Chrissy, breast is not a dirty word.
Chrissy: I can't hear you.
Roberta: Breast.
Chrissy: Can't hear you.
Roberta: Breast.
Chrissy: Can't hear you.
Roberta: BREAST!
Bully: Why don't you go home and play with your dolls.
Chrissy: The only doll Roberta's got is a G.I. Joe!
Teeny: Roberta, truth or dare?
Roberta: Truth.
Teeny: Just how big are your boobs now?
Roberta: Drop dead.
Teeny: She has to say, doesn't she, Sam?
Young Samantha Albertson: She doesn't have to say if she doesn't want to.
Teeny: Then can we see them?
Roberta: No, you can't see them!
Teeny: I don't have any real ones yet.
Roberta: Well, you'll get them, and you'll hate them.
Teeny: No, you're lucky, Roberta. Men love them when they're big. Look how big mine are today.
Young Samantha Albertson: They almost look real.
Teeny: They're filled with pudding.
Young Samantha Albertson: Pudding?
Teeny: The Wormers actually gave me the idea. Jello is too jiggly. Pudding has a heavier, more realistic texture.
Chrissy: What flavor is it?
Teeny: It's vanilla.
[Blushes]
Chrissy: It's not very big.
Roberta: It's only big when a guy has a hard on.
Teeny: And when that happens, they get this big.
Chrissy: What's a hard on?
Samantha: Doesn't your mother tell you anything?
Chrissy: I'm beginning to think she's been misinformed.
Chrissy: After all, a promise is a promise.
Samantha: When you're 12, without effort, you live in the moment. You don't regret the past or worry about the future, and in that moment, Teeny filled my heart with hope and comfort.
[Explaining sex to her daughter]
Chrissy's Mom: All women have a garden, and a garden needs a big hose to water it... or a small hose... as long as it works.
Teeny: Roberta, truth or dare?
Roberta: "Truth.
Teeny: Just how big are your boobs nows?
Roberta: Well just how big are your boobs?
Teeny: 36D and worth every penny.
Roberta: D, who knew?
Crazy Pete: Things will happen in your life that you can't stop. But that's no reason to shut out the world.
Samantha: We all used to try so hard to fit in. We wanted to look exactly alike, do all the same things, practically be the same person, but when we weren't looking that all changed. The tree house was supposed to bring us more independence, but what the summer actually brought was independence from each other.
Teeny: Now me.
[Reading from Cosmopolitan Magazine]
Teeny: Teeny, "You are a sexual magnet... attracting men from the four corners of the world. Pace yourself."
[Smiles]
Teeny: It's normal for things to be shitty.
[after Roberta punches Chrissy in the arm]
Chrissy: Ow! That hurt.
Roberta: Yea, well, you deserved it fart-ass!
Samantha: If you don't fall in love, you can't get hurt.
Roberta: But it sure is lonely all by yourself.
Samantha: Teeny's parents were country-clubbers that were never around - typical upbringing for actors and pathological liars.
Teeny: Oh, my God.
Roberta: What?
Teeny: I saw his penis.
Roberta, Chrissy, Young Samantha Albertson: Whose?
Teeny: And the balls.
Chrissy: You guys!
Teeny: Scott's.
Roberta, Young Samantha Albertson: Oh, my God!
Chrissy: I say we make a pact. Here and now. We're here for each other, always, no matter what happens in life. If Teeny goes off to Hollywood or I marry a rich doctor, we remember this day and this pact. Whenever we need a friend, we're here for each other. We can count on it. Always. No matter what.
Young Samantha Albertson: It's a pact.
Chrissy: All for one...
Chrissy, Teeny, Roberta, Young Samantha Albertson: And one for all.
Teeny: The home run mama steps up to the plate!
Young Samantha Albertson: Mr. Kent?
Bud: Oh please, call me Bud.
Young Samantha Albertson: Bug?
Bud: No, Bud, B-U-D. Bud.
Young Samantha Albertson: Oh. Well, BuD, you have a piece of food stuck in your teeth.
Samantha: [talking about the night in the graveyard with Crazy Pete] He said something that didn't mean as much then as it does now... He told me that things happen in life that you can't stop but it wasn't a reason to shut out the world...
[sighs]
Samantha: Wow... I realize that... I've been so afraid of the bad things that um... That I've missed out on the good... You know I didn't wanna come back here... But I'm really glad I did... I'd forgotten how much it helped to have you guys as friends... I'm really lucky to have this place... and each other...
Samantha: I decided not to tell the others about my father, call me a fool but I actually thought he'd be back, a wishful notion I held onto for years. At the time no one in The Gaslight Edition had gotten a divorce and the last thing I wanted was to be different from my friends.
Samantha: You can run from the dissapointments you're trying to forget. But its only when you embrace your past that you truly move forward. Maybe Thomas Wolfe never got to go home again, but I found my way there. And I'm glad I did.
Vietnam Veteran: I'm going to tell you something i wish someone would have told me when I was your age.
Chrissy: Oh yeah? What's that?
Vietnam Veteran: Your parents aren't always right.
Samantha: No shit.
Chrissy's Mom: I decided we should talk about what you asked me.
Chrissy: About sex.
Chrissy's Mom: You say that very casually, that's very scary for mommy. It's like, "BOO!" "AAH!" That's what sex is.
Samantha: Thomas Wolfe once said you can't go home again. Well, that's great for old Tom. But he wasn't a chick who made a pact with her friends when she was twelve to get together whenever any one of them needed each other. So here I am driving back to my childhood home in Indiana a place I can tell you I never wanted to see again.
[sighs]
Samantha: I guess a promise is a promise. Sure looks like I picked the wrong week to quit smoking.
Chrissy: For ten tree house Dollars I'd feel it to!
Roberta: You can't get pregnant from french-kissing!
Chrissy: I know that, beetle-brain, but it's common knowledge that if you tongue-kiss a boy, he automatically thinks you'll do the deed with him. They can't help it. They're driven. It's the male curse.
Samantha: Oh? And what deed would that be?
Chrissy: You know... planting the seed and watering the flower. Isn't that how it works?... The man takes his watering can and sprinkles it on the flower.
