“After Mom died, when it was just you and me, I remember having trouble sleeping. Never knowing where you were. But when I’d wake up in the morning, there’d be this paper bird, an origami crane, sitting next to my bed. And I never knew what it meant exactly, but I figured it was your way of letting me know you were checking in on me. Anyway, I looked it up. The crane. It stands for familial obligation. Watching out for your own. Maybe it’s my turn to watch out for you.”
