When I was a kid, I used to trade secrets like baseball cards. We moved around a bit when I was younger, and I wasn’t good at making friends. I was better at observing the kids around me, and analyzing how they talked to each other, which explains why I’m a writer now. But back then, all I really knew was that friends told each other secrets. I told a secret, I got a secret. I got a secret, I told a secret. The exchange rate was a perfect 1:1. Who is your crush? Who is my crush? We walked away none richer, none poorer. Or that was the hope.
