Preachie liberal neighbor
I have an annoying idiot neighbor who's always preaching to everyone about crap most people don't care about such as politics and his dumb ways of doing things because he's always right in his feeble mind. I could list all the crap that comes out of this fools mouth but instead l will tell you how to get back at morons like this. In the dark of night take a 2liter bottle full of bleach and pour it out on his grass that he spends lots of time watering because he feels it's ok to waste water on his grass like most hypocrites who think like him. You can write words or symbols or just dump it all out in any fashion, it will kill the grass. Perhaps you would want to dump it on his garden. Maybe you would like to dump it in his composting pit? It'll get the job done!
