Not for the first time, I wish, somehow, he never met Izzy. That when we met by the swings that day, I wasn’t so quiet and shy and weird, and was able to make him my friend before he could meet her. Claimed him in some way… But then I remember he’s in her grade. And then there’s the piano. Who would Mason even be without that? It’s as much a part of him, as it is my sister.
