Arms folded in dosidos? I don't "correct" it for three reasons:
1. I don't want to undermine the kids' model of what this dancing is all about.
In other words, I don't want the message to be "if you are doing THIS, then you
are wrong".
2. The folding of their arms keeps the kids from confusing the movement with any number of
other movements that do use hands/arms, and that's a win in my book.
3. Unless they are doing a demo where uniformity counts for something, IT DOESN'T
MATTER! In picking my battles, this one is way, way down on the list!
