Caro's right. She should be scared. Everything's out of her hands now. All the things coming Ava's way they won't be able to control, things she won't always ask for because she's a girl. She doesn't even know how hard it's going to be yet, but she will, because all girls find out. And I know it's going to be hard for Ava in ways I've never had to or will ever have to experience and I want to apologize to her now, before she finds out, like I wish someone had to me. Because maybe it would be better if we all got apologized to first. Maybe it would hurt less, expecting to be hurt.
