Teenager in the House

I have a teenager in the house with me.....

Does anyone know where my child is??

I understand that this is a generation after generation 'specialty'.  I understand that it's their way of finding who they are and what they want to be in the world outside of their home.

I don't understand why it can feel so 'uncomfortable' to me....   OH MY

When U know in Ur head why and how things are like they are, how do U relate it to Ur heart when Ur heart may not always understand?
