I went to a halloween party but it ended up being sort of awkward. Apparently the guy who hosted it invited all of his "usual" friends (that would include me), the people he could count on to show up to parties and contribute and so on, and we showed up. But it turned out he REALLY wanted some other people he'd invited to come, and he got increasingly pissed as the evening wore on and they didn't show. An hour and a half after the party was scheduled to end, we were sitting around and they did show up, no costumes, no contribution to food or drink or anything, and just sort of went on a tour of his house and then announced they were going to a sports bar and left.
To make things worse, they were just sort of casually insulting anything and everything...the other guests, the house, the stuff we'd brought, our costumes. So they were really kind of dicks and I don't know why anyone would seek their approval, but it was kind of made clear that we had been drastically demoted in importance so we got our stuff and left. And the guy hasn't spoken to me since
