an addendum to the "Stop" entry

I learned today from Meredith's teacher that they had NOT discussed that the stop sign was the shape of an octagon at school (she figured it was too advanced for these little guys). That means that Meredith either learned it from a puzzle she has with different shapes that we have done with her, OR more likely, from watching this clip with me probably 3-4 times because I LOVE it so much....
