re: Should I escalate a feud with my neighbor?

Had a feud years ago with a pretty crappy neighbor. Bad dude who was perpetually angry. Let my emotions get the better of me one afternoon when mowing grass. He proceeded to yell at me and call cops. Cops sided with me. Nothing in the end.
Fast forward about a year later, he got angry at his wife, shot and killed her, then himself in their home. I’ll never forget the daughter running in the street after screaming for help. With how angry he was perpetually, that event could have been me getting shot a year earlier.

Long story short: don’t perpetuate the fight. Make concessions. Don’t worry about the fence. Pay attention to “his space” in the future. Life’s too short.
