Q&A for How to Deal with Friends Who Invite Themselves over Without Asking

No, that's extremely rude, and you should tell them that. Say something like, "I understand if you don't want to invite me out to dinner with you, but it's very rude for you to expect me to host you at my house after you've gone out."

When they come over, don't let them in and have your parents answer the door and tell them to go away.

Be polite, but firm. Explain to her that if she ever does this another time that your home is your space, or that you are busy and she isn't welcome without your express permission. Tell her she wouldn't like it if you did the same thing to her if the roles were reversed.

There really isn't. She is probably going to be offended either way. If it means a lot to you to let her know that her behavior was rude, just tell her this directly. The honest way is always the best, just make sure you're polite when addressing the situation.

Find new friends. There's pretty much no excuse for that behavior. If you really want to give them another chance, have a talk with them about the way this made you feel and see if they at least apologize. Then it's up to you how you want to handle it.
