Teenagers

I have a teenaged daughter and it is very difficult to live with her.
She doesn´t want to listen to us.And she always think we are mean to her.
She and her sister are quarrelling all the time, every minute.
I know that this is the age but I want to make sure she understands she has to change a little.
Today we had a big talk but she is always in a bad mood.
We think we know our children but their behaviour change and we have to know how to manage this.
The question is when we ask ourselves when is normal or not that behaviour.When we have to control this.I don´t think we have a guide to do this.
I know we have to speak more with them,don´t ignore them,avoid making jokes.I think they are confused about their thoughts.
Rebelling in teenagers is often symbolic.
They want to look grown up and impress their friends.
Teenagers have reason to be confused because they are part of the adult world in a biological sense, but are still not permitted to do many of the things that adults can.
If parents disapprove, it often makes teenage behaviour worse and arguments are common.
