I'm not sure if I've ever told you this story, but the chances are high. Back in the day of long ago, my sister and I took break dancing lessons. Yes, that's right. And like most activities that require a combination of physical prowess and coordination, I was absolutely terrible, even by little kid standards.
I remember on the last day we all got in a circle to demonstrate our new skills. I opted for the only thing I thought I could do rather well (ask me to demonstrate and I think you'll see that I thought wrong) – that move we professionals call The Arm Wave. Everyone was really polite, though I don't recall any sense of accomplishment.
