This happened to me last month when I was swimming in a hotel pool. It was early morning and I was the only person in the pool and this dude sat down on one of the deck chairs and just started talking at me and wouldn't shut up.
I kept swimming laps and I have some hearing loss so he'd fade out and I got further away from where he was sitting and then fade back in as I turned around and got closer.
He acted as if I'd said to him PLEASE TELL ME ABOUT YOUR ENTIRE LIFE -- AND YOUR WIFE'S ENTIRE LIFE - AND PLEASE TELL ME EVERY DANG THOUGHT THAT CROSSES YOUR MIND.
I guess people like this just go through life blathering at people?
