I'm going to kick a guest out of my party for not socializing with other people.
Why isn't he socializing?
He keeps talking to people on his phone.
Kicking someone out of your party for not talking to other guests is socially unacceptable. You can't force people to mingle with others. You have to accept that some people are just shy and not very talkative.
Why can't people observe social norms. I should put my foot up his ass. Fucker is disrespecting me by not talking to my guests.
Maybe the person is just shy. If you go up to him and try to get into a conversation maybe he will join in. Kicking him out isn't going to solve anything.
