Kids being chocked, true stories…
My sister started teaching some 35 odd years ago in a class of 3 years old in a neighborhood where the kids would say "bugger off, you cunt" to one another as easily as others say "Hi, how are you doing?" Once one of her student was sobbing desperately "What happened?" and the little girl pointed at another one "She called me naughty!"
A friend of mine teaching in pre-school (age 3) asked one of her boys "Where do you live?" (in French "Où tu habites?" pronounced "où t'habites" when you speak fast) and the boy said "Là!" ("There!") pointing at his groin because he'd understood "Où ta bite?" (Where('s) your cock?)
In both cases, guess who was shocked!
IMO many people tend to want to protect their own sweet vision of childhood. If they want to protect the actual children why don't they use some parental control software and/or do they let the children surf on the internet unattended?
