" Tired from my all-nighter with my friends, I just kept walking, my head bursting with their conversations, the things I had learned-Laura had had to take the morning-after pill-but none were as loud as the conversations I was having with myself in my head. That, I could never switch off. I don’t think I’d ever thought so much, and talked so little, in my life. "
