A little later I found M and J sitting at the window. J lost interest pretty quick, but M was totally engaged by something. I was thinking "what in the world is so interesting out there?" A couple minutes later M came running to me saying, "Mom, you have to come see this. It's just too cool."
It was (in her words) the "silly disappear man." She was watching a man across the street mow his front lawn .
She said, "Watch Mom! You see, he's so silly. He walks in a straight line, turns around, then he disappears. But he'll come back. Wait. Wait. See! There he is again!"
