All the time, I'm afraid the thing that happened that made it all right for my mother to kill my sister could happen again. I don't know what it is, I don't know who it is, but maybe there is something else terrible enough to make her do it again. I need to know what that thing might be, but I don't want to. Whatever it is, it comes from outside this house, outside the yard, and it can come right on in the yard if it wants to. So I never leave this house and I watch over the yard, so it can't happen again and my mother won't have to kill me too.
