My kids don't cuz I won't let them out of my sight mate, call me paranoid if you wish, But I won't let my kids go off and do the things I did because I don't feel safe letting them out.
I certainly don't remember kids telling teachers in my school to F**k off etc, they do in the primary schools now, let alone what ever secondary schools are called now...
maybe I was a saddo mate, but I was a happy one, and it didn't do me any harm
