So back in my parents house if I had a friend over that my parents did not want over they could ask the person to leave. If the person didn't leave it would trespassing (despite me wanting my friend over). Yes? So how does the whole situation work out when you share a space with someone who is your roommate. If one person has someone over that they want over and the other person wants the friend out of the room and ask them to leave? Is it then considered trespassing as well? Thanks for any help. I just want to know how this whole things plays out. I'm not talking about just oh go talk to your roommate that it's not ok... but the action of him having someone over that you don't want over and you ask that person to leave and they refuse. Is it considered trespassing or something like that?
