Sometimes I truly resent having to be seen with her in public. The rest of the time I just feel jealous. I don’t know how to say no to Pina. When we were in fourth grade she made me play a game where you scratched your hand until it bled. Then we did a blood pact to be sisters. But lately we’re not so similar: everything she does, everything that happens to her, makes me jealous. It’s all so much more exciting than anything going on in my life. And I don’t know when this started. Actually, I do. It started when her mom reappeared.
