My wife and I are not particularly gregarious people. So we have no idea how our ten-year-old son learned it.
Case in point: today we were at the pool. We were enjoying our time when the local college soccer team showed up and monopolized a large portion of the pool, and doubled the volume. I was finding myself a little annoyed at their presence, but they weren't doing anything really objectionable besides being a lot of people.
And then my dear little boy worked his way into the middle of this group of twenty-something men, and organized them into a game of Marco Polo with him being the first Marco. They were all having so much fun and he caught one of them in just a few minutes.
If he weren't also a sweet, kind-hearted soul, I'd worry about him growing up to start his own cult, because he would be wildly successful at that.
