Hello everyone, A few month ago, we moved to this apt building, and there is a unit a few feet away from us. We have seen a myriad of men going in there; for the last 3 months alone more than 90 men. Late at night a man comes in for a two hours and leaves, and never comes back again. Next day a different man, and different car, and so on and so forth. During the weekend two men a day. Men look pretty young in their 20s. Now why I am asking this question on here? There is a girl who lives in there in her mid forties, she wears scrubs and we were told by the management that she is a nurse. She doesn't talk to anyone in the building, and leaves and comes back at odd hours. We honestly have tried to turn a blind eye and deaf ear on the whole issue for months, but it's really something happening daily, and can't be ignored. We are a couple in our sixties, and don't want to cause any problems to anyone. I've talked to the management, but they didn't care and told me she pays the rent on time. I'd like to know what you guys think, and what should I do?
