Huh, I never noticed they disappeared, but they were definitely there before.

Maybe it's not clear, but are you going to the party? Sounds like his best friend really wants him to go if he keeps inviting him. But I don't blame you for being upset with rude guests. I can't stand being around rude people either.

Maybe the party won't be so bad? I've been to parties with some people I didn't like, but the party ended up being ok because I avoided them and talked to the people I knew. You can also leave early if it's really that awful.
