The number is the same as my apartment, not just random.
Look, if your friend lets you spend the night at her apartment and sleep on her couch or the floor or whatever, please don't have sex on her couch. Even if it's 4:00 in the morning. You never know when a roommate's gonna wake up and go searching for her antibiotics and catch you doing it on the couch and be so grossed out that she can no longer sit on that couch, which, by the way, is the better of the two couches. For crying out loud.
