A..hole neighbors

I may be way off-base here, but I bet the old man is lonely and misses being around people and contributing to his neighborhood, and he likes you. Even though he is very annoying, you will miss him when he's not around anymore. My grandpa used to get on my nerves but I regret feeling that way, now that he's gone. Maybe your neighbor has mental problems too. I guess I wonder if someday I will be that annoying, lonely old guy lol.
