I remember having a neighbor like that many years ago.
My mom and I received an annoymous(sp) letter in the mail box
complaining about my dog barking, than a warning
letter from the animal control stating that a neighbor complained
about my barking dog. It wasn't even my dog, (my dog was kept inside and rarely barked)
It was the next door neighbors dog who was kept
outside that barked all the time.
Their dog's barking ecco'd in between our two houses.
We all new which neighbor complained too, even
though he never signed his name to the letter.
He use to shoot a bebe gun at birds that landed on
his lawn, and if you dared parked your car in the street
in front of your own house he would leave a nasty note on it.
Seems all neighborhood have at least one bad apple.
