I nod. Christina regards me as if I've done something extraordinary just by staying alive and I wonder, again, what she's had to witness without me. "Eighteen and..." I pause, realizing that I'm not eighteen and a half. "I'll be nineteen, actually, in a week."

It's strange to think about, even to myself. Then Christina smiles and I breathe a little easier. "Yes, a rabbit. You'll understand when you meet her."

I pay for and collect our coffees. "But we should go to the train station first."
