How embarrassing. As if you don't have enough to worry about being a kid in the world, interacting with other kids, but "Hey! Let me see your teeth!!"

I had a biology teacher 30 years ago that did the same thing to me. I wonder if this is where he learned it from.

The addition of television, computers etc does not take away from the basic design. Of course the elimination of the potbellied stove was certainly a good thing.
