You come home one night from work and there's this guy sitting in the hallway. You don't know who he is, and, come to think of it, you don't even know who your neighbors are in the apartment building, much more the floor where you are at, where this guy is sitting. He doesn't look unkempt, but he's sitting there, and he looks like a mean character, but you don't really know that. You assume that he lives in one of the apartments on your floor and probably got locked out, or something, so you let it go at that, and retire for the night, but the next morning, you go out to go to your favorite bakery/cafeteria, and there he is, asleep on the floor. You tiptoe past him and go about your business, and you come back, and he's still there, asleep, or at least laying down on the floor, because his feet are like tapping the air. You go into your apartment, but you're bothered. You've been in the hood for 9 months, and found the area generally peaceful, with working folks, who leave each other alone, but this is something new to you. Do you go and call the leasing office and tell them about it hoping maybe they'd send some sort of security to take care of this ? If you do, the next problem is will they handle this discreetly in such a way as to not put you on the guy's "folks-to-get-even-with" list ? Do you call the cops ? Do you talk to him ? Maybe offer him something hot to drink considering he's been on that cold floor all night long ? But what if the guy was a wee bit off his rocker and attacks you ? What would you guys do ?
