It's 2:30 in the morning on Monday night and my roommate (who is also one of my closest friends) just brought a random guy home. They were loud coming in (and are currently having sex which I can hear through the walls) and she woke up myself and another roommate. I can only assume the other 2 roommates heard her as well since we have thin walls. We ALL have class tomorrow morning, bright and early. This is a bit of a vent, but also I need advice. She's done this before but never on a weeknight, and we (the rest of the roommates) have never fully condoned it, but we're all good friends and have no major problems with her bringing guys home. However, she's always loud, she rarely plays music (and even when she does it doesn't cover up the noise), and it's almost always random guys we don't know at all that she's bringing in to our house. That makes me nervous, for us and for her. HELP?!
