If I have cause to use the sidewalk while this inconsiderate narcissist bastard is sitting there, I might have some choice words and a smack upside the head for him.
Walk by him in wet cloths and DRIP on him ..or let the kids run around..if you don’t have kids rent or borrow some!!! LOL
The correct thing to do is to say, “HEY DICKHEAD. THIS IS A SIDEWALK! MOVE IT!”
