The last time I wasn't polite to a man he threatened to ruin my life, drive me out of my home, kill my dog, etc. All I did was throw his stuff back into his yard, stuff he had thrown into my driveway. Yeah, that was my next door neighbor. And he won, I'm selling my house at a loss and fucking my credit just to get away from him
Edit: a couple months before that he tried to break into my house because he wanted something and I wasn't answering the door. And a few months before that he had literally pushed his way into my house following me in. Some people are nuts, and so need to be treated carefully. I was just completely at my limit with him, and should have called for backup before that confrontation that pissed him off
