Why teachers forced us to CUT our NAILS?

I figured it out while watching some of the stuff you want to see, but don't want to see ;)

As almost all of the teachers were married, so they knew what happens down the road from hill to the middle of human body.

Those genitals in the middle of female body are so, so much sensitive to external stimulation and injury, that even if touched without proper oiling, can hurt the unaware girl very badly.

So to prevent any mishappenings with that hot hot beautiful girl, kids were thrown into a habit of cutting nails on weekly basis.
