It's one of the worst-kept secrets of family life that all parents have a preferred son or daughter, and the rules for acknowledging it are the same everywhere: The favored kids recognize their status and keep quiet about it - the better to preserve the good thing they've got going and to keep their siblings off their back.
I like to tell kids that I started thinking about stories when I first started reading stuff like Dr. Seuss and 'Go, Dog. Go!,' thinking, 'Oh yeah, that's funny. I'd like to do that.' And then writing throughout school, but at the same time I was studying pre-med stuff, because my mom told me I should be a doctor.
