The next time there is a dance at school, volunteer to chaperon. Your children will have a fit, so be prepared with an excuse. Screw up your courage and walk across the dance floor. Break through the circle of bodies that surrounds the dancers like a force field and watch them. The kids in the middle of that circle will probably be ''freak dancing,'' and you have to see it to believe it.
Freak dancing makes dirty dancing look like a cotillion.
It is beyond suggestive. It looks like the real thing. Boys and girls are doing more than thrusting hips and pelvises. They are grinding genitals. Back to back, front to back.
