It seems to be the norm...teenagers swearing at each other and threatening behaviour. Luckily for me, my three eldest children didnt seem to swear in front of me. They were respectful to myself and other adults, and knew the boundaries. I'm not going to kid myself and say that they didn't swear, but at least they knew their limitations. I think a lot has to do with parenting these days, it seems to have gone by the wayside. Teach your children right from wrong, have open lines of communication with them, and you cant go too far wrong.
