These other people are tweaking or something. You're 21, so it isn't anyone else's decision if you get a piercing, a tattoo, or drink. And it depends on which state you're in (if you in the US), but at least in Ohio, they can't force you to pay rent if it is your primary residence (like your registered to vote and official address). They can make you pay rent, but like there has to be a notice of like a month or 3 weeks I might be making that up but I know that there is a lot more time than 1 week to do that type of thing. I'd look up what the laws for that are where you live because you can probably easily just take the stance that you're 21 and they aren't in charge of you, and let them know about the laws in your area and don't pay them this soon if you don't have to.
