As adults, we've seen so much before that we often turn the pages of a picture book without really looking. Young children tend to look more carefully.
Worrying can be a kind of caring, and as such is a healthy part of a balanced emotional life.
The first things I remember drawing were battles - big sheets of paper covered in terrible scenes of carnage - though when you looked closely, there were little jokes and speech bubbles and odd things going on in the background.
I grew up with an older brother who was always stronger and faster and better than me at everything, but I was close enough in age to try and compete, so we had a competitive childhood.
My dad never decided what he wanted to do; at times he fought in the army, was a teacher, a boxer, a light engineer, and a then a publican. My mum was a traditional housewife and mother. They showed my brother and I unconditional love.
