Or maybe they're getting even with the neighbors who's dogs barked all day and night, or the guys dog that cra##ed in there lot, or neighbors screaming kids running through their site over and over, or the the blaring music from various neighbors all day and night, or the drunks up until 3am hootin and hollering, or those using hammer drills to lower their jacks. The list goes on and on I'm sure.
It isn't really worth the getting upset over looking at the big picture. I'm sure we've all done something to cheese someone off.
