I lived in a pretty foul place for a number of years.
I've had neighbors that play music in cars all night long, wake up to broken bottles being smashed on the street, fights, domestic abuse cases, etc.
My "neighbor" for about a year were 7 mexicans in a 2 bedroom home. They spoke no english, so I had to communicate with them on multiple occasions with a translator to explain to them to stop sleeping/loitering on my front steps all night.
I had a guy that liked to run his boat (no lakes here) anytime he felt like it but his race car took the cake. Every day 30-60 minutes of my night were filled with window-shaking revs on his car as he apparently had a psychological need to hear, smell, and feel the car. Usually, he was completely drunk.
Heck, I'd had given anything to have a guy WITH A JOB live next to me.
Postscript: I live in a nice, friendly community now where people have better things to do than annoy each other. I can't complain anymore!
