My big brother, you see, is so cool and beautiful and smart and kind. He makes me anything I say I want to eat, reads me books when I can't sleep, sleeps with me, and comes to get me if I get lost. If I ask about a hundred times, he'll even pat my head. He doesn't call me Misha, but I think that'll come true someday too. After all, he's my big brother who's so proud of his scars!"
