neighbours from hell, page-46

Find out who is the "leader of the pack"

See if you can get him on his own and talk to him.

At time with these guys strength is in numbers, on their
own things can be entirely different..
Do not take a backward step if you can isolate him.

If this is not successful for the sake of the family
and your peace of mind move to a different location

I certainly feel for you, best of luck
