Lifes Like That

This is a serious question for you all.  Why won’t kids listen at home, but they have no problems listening to their teachers at school and absorbing each and every word they say??  Here is an example of what I’m talking about.  My daughter who is in grade 4 has really long hair.  Every morning it is a serious fight to get her to brush her hair and put it up in either a head band or a pony.  But, when her violin teacher tells her that on violin days she needs to have her hair put back (so it doesn’t get tangled in the strings), she has no problem putting her hair up and back.  Matter of fact, this morning, she went to school with her hair in a pony and had a head band on.

So, my question to you all is why do kids behave like this??  Why do it for one with no problems, but fight with us over the same exact thing??
