My neighbor keeps his trees trimmed, and his dog out of my yard. He doesn't park in front of my house, either.
The problem is that I don't like it when he goes in and out of his house during the day, and I like it even less when he goes in and out during the night. Don't even ask me how mad I get when he uses his fancy schmancy electronical garage door opener instead of the front door.
Also, his porch light is way too bright. I think it's 40 watts, but could be 60. Maybe even 100, I don't really know.
Oh yeah - he has zoysia grass, and I hate that.
And another thing - he has these thingies that hang at the edge of his roof, and when it rains they collect a lot of water and divert it onto his yard. This REALLY pisses me off.
He also keeps a big black round gizmo on his deck, and sometime he sets it on fire and puts some sort of meat on it. The smell is awful. What ever happened to cooking in your kitchen and sparing the rest of us from knowing what you are going to eat that night?
PLUS when he does this he drinks beer, which is a sin.
I'll never figure out why people can't be good neighbors and get along with me; I don't ask much, and I'm not petty like they are.
