I grew up in the Cayman Islands. I didn't play video games or watch TV. I would basically come home from school, throw down my backpack, grab my machete, and go hike and chop down trees to make a fort.
My mother told me to be a lady. And for her, that meant be your own person, be independent.
Inevitably I draw on my own relationships when I write, so if I'm writing about a fight between a husband and his wife, of course I'm going to think about a recent fight with my husband. Or if I'm writing about sisters, of course I'm going to think about my sister.
