Sorry to say, but I don't believe your son. When you eavesdrop on him, he is more than likely inside of the house or around the house right? Of course he won't use the f-word when your in the same house or yard as him. I was a 10yr old boy once, little boys lie and swear like crazy.

Beside the point though, the school had no right to suspend him when outside of school or not even on school property. Even if he did curse at them, does that give them the right to do that? No, in my opinion it doesn't.

10yr old boys aren't as innocent as they seem and they will say whatever they want as they don't understand consequence.

I remeber when I was 13, we would always skateboard at the church lot a few blocks away from school. One day a teacher from school asked us nicely to stop skating and respect the property. Well then, what dod I care, so we beaked her off and told her off. The following Monday, me and 3 of the buddies all got in-school suspensions because we told a teacher off.

Same thing pretty much. They seem to think when you sign up for the school year that they have total control and dictation over you for that year, wherever you are.
