I'm going to kick a friend out of my house
Why would you do that?
I was invited to a college party and I don't want them to come along.
It is wrong to just kick out guests when you feel like it. You should provide them with an alternative place to go while you are away or take them with you.
I don't want to do it. Get out or I'll call the cops.
That seems pretty mean to do that to a friend. Abandoning people can make you seem cold and uncaring. If you don't want them to come along, you don't have to disclose your plans, but you should try and be more accommodating.
