what about TEEN girls?

I received this email message recently:

"...Anything on TEENage girls? I have noticed a large gap in the willingness of many parents of teens to discuss the realities of raising a teen...everything is either "really good" all the time with their teen, or "really bad". I also see a huge difference in my daughter's take on individual classmates, and feedback I get from parents and teachers; the adults say everyone loves her, she is well respected, and she gets elected to many leadership roles. On the other hand, she has a lot of critical things to say TO ME about many of the classmates....wondering if she is just venting to me, or if she is "acting" happy at school and is not...I try not to be critical and just let her have her say, but then wonder if there is something more I should be paying attention to...."
