I'm in northern ca in a nice neighborhood with other types of neighbor problems, but thank goodness not the ones you're describing. I'm sorry, no one should have to deal with that. I have no answers, but many younger persons these days have no respect--none for property, adults, themselves even.
I teach (I guess I should say taught) and witness that in the classroom with second grade students children masterbating and writing notes about kissing and having sex (SECOND GRADE!!!).
Anyhow, I'm awake and have been, because I was fired Friday from that teaching job. I'm an at will employee (Charter School stuff), so I was given no reason. I'm sure it's because I couldn't ""control the students. How about the parents taking responsibility and having my back? No way.
Good luck future America.
and Good luck to you with your neighbors--I hope the party's over by now and you're getting some sleep.
