"You don't tell me what to do."

Exactly how much do educators have to put up with nowadays?  Many students think they can say whatever they what to whom ever they want.  Just recently a teacher asked a student to do something and the student replied with " You don't tell me what to do."  I would say I'm surprised by this response, but very little surprises me.  Now to top it off, when mom found out about the incident she wasn't upset with her child she was upset with the fact that the teacher verbally reprimanded her child.  Mom even went on to say that she thought the teacher needed to apologize for how he treated her child.  You have got to be kidding me.
