Hey Guys- So, I live in the upstairs unit of a small, quiet apartment complex and have a new neighbor down below. He has been living there for several months now with a young girl (probably about 10), who I assume to be his daughter. I don't think there is any sort of motherly figure present in the home, but I rarely see them to really know. Over the past several months, I have seen the man maybe 3 times and the daughter once outside the apartment--I have never conversed with either. Over the past few weeks, they have gotten EXCEPTIONALLY noisy. At first, it was nothing but loud television playing, but it has gotten much worse. I constantly hear the man yelling at the child, followed by her screaming/crying back, and then generally I hear multiple loud thuds and door slamming following this. It is pretty much on a daily basis at this point. However, several hours ago, I was sitting here and all of the sudden hear the man screaming "Put the knife down". At first I figured I could not be hearing this right, but he kept yelling it over and over and I am quite confident that is what he was saying. Since then, it has been constant yelling and screaming back and forth, followed by slams and thuds. This is obviously quite upsetting and obnoxious, and I am concerned for the girl's safety. I don't know whether or not I should call the police if this continues, and I must admit that I fear for my own safety if I decide to. I am 23, live alone, and am about 110 lbs. I do not want this guy assuming or figuring out it was me who called and starting problems with me. The unit next door to him is vacant, so I am sure he would deduce that it was me complaining. What do you guys think? I feel awful for this poor girl, but I don't know where to draw the line between what is and isn't my business. Sorry the post is so long, but I would really appreciate any advice!
