It definitely is karma.
Here's my contribution to this thread:
about 8-10 years back I used to frequent the downtown club scene at Axis on Lansdowne St. I stopped VOLUNTARILY when I turned 40, yet I wasn't a lounge lizard. Anyway, this one Saturday night after a rousing night of drinking and dancing I was heading down to Kenmore Sqaure for some snack and a taxi home. While heading up Lansdowne St. there was a crowd gathering just inside the lower parking garage across from the Fenway's Green Monster. There was one of those make-shift drum street performers really getting his groove on, and doing a good job at it.
The fun for me was that there were a couple of couples standing next to me (good looking college chicks and their boyfriends). Well, at some point one of the guys who had been standing behind his girl decided to move over to get a better look at the drummer, and his girlfriend didn't notice. Instead she just move back into who she thought was her guy, but was actually me.

That in itself was comical enough, except that she was feeling a little frisky, and decided to give her man a frisky reach-around to fondle his junk.

You can only imagine the look on her face when she noticed her guy standing to her right, and turning around to face me, grinning from ear to ear.

I thanked her and proceeded on my way, noting the many shades of red on her face.

Then there's my first flight on Airlingus back in '92, but that too is for another day.
Some say that we make these things up, but if you haven't lived our lives, or walked in our shoes, how do you know?
