You never know what you're going to encounter at the gym, including in the parking lot.
Yesterday I was getting out of the car and I heard this woman shouting. I looked around and there she was on her cell phone, screaming into it: "I'm not fucking married to him, I'm still fucking married to you!" The craziest thing about this was that she was about 25 yards away sitting in her car with the windows rolled up and I could still hear her clear as day!
Last week when I was walking to my car I overheard three older folks having a rather confused discussion. Seems the one fellow couldn't find his car--in fact he couldn't quite remember what his car looked like! Poor old guy, it was pretty sad. I thought about asking if I could help, but I figured between the three of them they ought to be able to locate it. And I tried to bear in mind that I'm going to be an old person too some day.

I suppose the moral of the story is always try to remember which car you drove and that a car is not a soundproof booth.
