Maybe you can resolve issues with people parking in your space by deflating their tires. You can put up a nice little note saying that since they had dropped into your space you knew they wouldn’t mind supplying air for your tires.
In this area, I could get killed for that, and there are enough people who don’t like me that they wouldn’t have any problems trashing my vehicle beyond repair. No thanks. I’ve never been vindictive, thinking “what goes around, comes around,” so I’m content letting Karma take care of my light work. And it will, eventually.
Until I can get $1500 toward a house of my own, I’m trying not to make waves.
