I don't think anyone here is un-invited to that party. If you don't want to go, that's a different manner, but I don't think they're going to throw anyone out.
I'm not going because it's in Tacoma, which is hard for me to get to, and because my finger still hurts and I can't bowl. Otherwise I'd be there nomming waffles with the best of them. (Or the worst, maybe. I actually have a very low sugar tolerance.)
