Maybe... just maybe... there is no problem at all. Maybe he's not sick, hard of hearing, a grouch, or anything at all.

Is there some sort of rule that everybody has to like everybody here? If somebody doesn't wave, or give you a big smile you have to make cookies, or a nice cake or something? How about handing him an envelope full of cash?
If he's throwing stuff on your lawn, bad-mouthing you around the neighborhood, or peeking in your window... you have a problem. Otherwise...

I have nice neighbors on both sides, across the street, and up and down the block. The guy directly across... not so much. Am I concerned? Nope... who cares? Did you like everybody at school, at work, everywhere?

On TOTV a while back a lady was upset that when riding her golf cart she waved to 75 other carts and only a few waved back... Give me a break.
