I think we should wean Grandma.

She knows Daddy better than I do. I think it's because she's felt since we were children that our Daddy maybe loved me more than he loves her. This isn't true, and she knows that now--people love different people in different ways--but it must have seemed that way to her when we were little. I look as though I just can't make it, she looks like can't nothing stop her.

I think that's why Sis was always in front of that damn mirror all the time, when we were kids. She was saying, 'I don't care. I got me.' Of course, this only made her come on stronger than ever, which was the last effect she desired: but that's the way we are and that's how we can sometimes get so fucked up. Anyway, she's past all that. She knows who she is, or, at least, she knows who she damn well isn't.

We never fail to come across with undying adoration, whether or not you deserve it, and we can't take our lives as seriously as yours. We snuffle up the crumbs from your table on the rare occasions you notice we're alive.
