I've never been caught, well, not un-intentionally!

but when I was working at a summer camp this 9yr old kid fell asleep in the back of our bus on the way back from a field trip. He started pulling at himself while he was sleeping! I felt so bad, the other kids teased him for the rest of the summer.

this thread also reminded me of a tori amos song about when she was younger she used to be in the basement of the church while her father was given the mass (her dad's a priest)
that song always makes me hot...
