Bird making in kindergarten. Usually, when I stitch with the little ones, I give step by step verbal directions, often holding the cloth with them, guiding their needle, etc. Mid-birds I found that for most of the kids, if given the whole picture, telling them what the goal of the needle was, and if I let go and got out of their way...they were able to figure it out (with a little needle re-directing).
I suppose that's true for a lot of things in life.
And about the flash mob . . . there were 30-40 of us dancing at a the Seattle Brain Cancer Walk. We burst into our moves (some moving much better than others) in the middle of the crowd just before the walk started. It was a lot of fun, and great to participate in something uplifting at a very emotional event. And no one minded that a few of us were not quite in sync at all times, or at least they didn't tell us!
