I feel a bit of the angry old man sometimes when I'm in a restaurant, and people at another table feel the need to be unnecessarily loud, particularly with exaggerated laughter, as if everyone in the building (and some of those next door) has to know that they are having a good time.
He has since died, but the guy who lived across the street from us - a really nice guy - was an auctioneer, and he would offer whatever didn't sell at auction for sale from his yard, and people would sometimes park directly in front of our driveway, which is something I would assume anyone would have the good sense not to do. We still get that sometimes when they are holding a concert or something in the park a block and a half from there. Who can grow old enough to drive a car and not know better than to block someone's driveway?
