I'm not going to invite my friend to my birthday party
Is it normal to invite friends to your party?
Yes, I've had birthday parties in the past few years where I invited some of my friends.
It's rude not to invite your friend to a party you're having. You should invite your friends to events you're celebrating.
I don't want my friend to attend since I'm turning 18. I want to party hard and my friend isn't going to approve it.
I still think that you need to invite your friend to this party. I think it is a little foul to not invite a friend to such a big milestone.
