I've lived in this pretty nice apartment building for almost 5 years. ALL my neighbors are quiet and respectful. A little while ago, I started being woken up late at night, or early in the morning by a door being slammed shut really hard. I didn't know who was doing it. So, the next time it happened, I dashed for my front door and and went into the hall, to see this arab guy walking away from his apartment. He's diagonal from me. I wasn't going to shout out loud at him in the hallway, so, I wrote a note, telling him that I have been woken up several times to his slamming his front door shut. He wrote me back saying he wasn't aware and apologized for the inconvenience. Since then, he was quieter for a couple of days, but is back to slamming his door shut. It seems like this fucking guy doesn't sleep and I hear other people in there sometimes (he lives in a damn studio) and has no consideration for his neighbors. He's new to this building (The guy before him never did that). Not sure what to do at this point. Building management won't do shit, so that would be a waste of time going to them. I mean, how fucking hard is it to close a door (your damn front door) without smashing it closed every time? Suggestions?
