Apparently mothers and teen daughters cannot be friends

"18. Can a mother be friends with her teenage daughter?

No. Most teens aren't ready for anything close to a mature friendship. According to current research, the brain continues to develop into a person's 20s. Mothers often want to befriend their daughters; fathers, their sons. But this is not in anyone's best interest. Teenagers need to form identities distinct from their parents. That means: lots of privacy, even some secrets. It's usually easier for a teenage girl to befriend the friend of her mother, and it's usually best for the mother to leave it at that."

WHAT? LOL Who is writing this article? I am totally besties with my mother, we listen to the same music, basically like the same movies, have the same sense of humor, we are two peas in a pod!  I think it's a two way street.  The mother has to be respectful of her teens privacy and be supportive while her daughter needs to honor that trust and be appreciative of said support.
