Discuss OronD's answer to: What turned my 16 y/o daughter from my best friend to my enemy?

You received an excellent answer (thumb up AdviceMamma).  I would like to add:
1.  That is a typical behaviou of a 16 y.o.
2.  Don't forget that she is at a very confusing age. 
3.  She is turning from a girl to a young woman. 
4.  She is confused and is checking the limits and testing
     her powers. 
5.  She is doing the first steps towards independence. 
6.  But she still needs you (both) desparately.
7.  Accept her as she is, be there for her, help her and
     try to understand her. 
8.  take some distance and hope that she'll change her
     attitude as soon as she becomes more settled.
9.  You have good reasons to believe that that present 
     situation will improve dramatically (I'll asay within 2-3 years).
