I remember being in high school and my mother would say, "What about such-and-such boy?" I'm like, "Oh mom, he's too nice," we don't like the nice boys when we're 16. I'd say, "He's not attractive," and she'd say "All young people are attractive." And they are, and I get that.
I like exploring both the light parts and the dark parts of a single person. And all of those shades tend to come out most acutely in stories about families.
