Wal-Mart checkout
The check out lady at Wal-Mart's said, "Is this yours," as she picked up my upper bridge from the conveyor belt. Thank God! I thoughts it had dropped into the urinal in the men's room. "Thanks," I said and put it back in my mouth! Full disclosure: Actually, this hasn't happened yet, but I wouldn't, if I were you, stand near me if you see me start to sneeze.
You know you are really starting to look old when someone comes over to you at a Civil War reenactment...and thanks you for your service!
You know you are starting to look REALLY old when....a little old lady with a walker offers you her seat on the bus. You thank her profusely...and sit.
You know you are starting to look REALLY old...when you go the funeral home for a visitation..and the solemn man at the door asks you..."are you here to pay your last respects……. Or turn yourself in?"
