Absolutely right. And just as true is the fact that he has every LEGAL right in the world to BE that nasty. The fact that he would choose to do so simply indicates a misanthrope of sociopathic proportions, a man the neighborhood would be wise to shun. And if a few ... hints ... were dropped that he might be more comfortable in a different neighborhood, that would be doing him a favor.
It's similar to that neighbor that wrote the cuss words in his foot tall grass after they complained to the city about the grass height. LOL
