I'm going to threaten to kick a friend out of my house
Is there a reason to kick them out?
Yes, I want to be alone with my other friend.
You shouldn't threaten a friend like that. You need to work out your differences.
It's okay. They will be fine. I just want to be alone with my friend.
Talk to your friend about it and he'll likely understand; threatening him will stir up a lot of bad feelings.
