What do you do when hear neighbors or people yelling and arguing with each other?

Yelling between 10 pm and 8 am, may be a noise ordinance violation, Cops on the NON-911 line.

Yelling between 8 am and 959 pm Live with it. UNLESS you hear gun shots, smashing, or Shrieking. Call 911.

Learn to love your neighbours, with all their faults.

I mind my own business

There is about 30 feet between my house and the house above me, and about 50 feet between my neighbors below me.  If I do hear something through 2 brick walls it would probably involve gunfire.

I guess it would depend how loudly they are arguing. If it just sounds like silly fights I'd probably try and chat to them about it myself if I  had a good relationship with them. But domestic violence can lead to people being killed. I would call the police if it was really bad. 

call the police?.....i hope you would appreciate me calling the police everythime you decided to raise your voice.....what a tit

Me i stay out of it, it has nothing to do with me and unless there is a real danger to people..
