@maxdancona,
Yes of course she is. But she is just shy of turning 18 and as a parent is by innocent child.
I know she is aware of adult things - but honestly she isn't even like most typical teenagers - she likes to be conservative. She stopped going to team dinners with one of the varsity teams she played on because in her words they said inappropriate things.
She is sort of more mature and less mature in many ways - more mature in that she doesn't get dragged into drama, knows what she wants and doesn't follow the crowd. She knows herself. She is less mature in that she likes younger kid things - like movies, entertainment and what she enjoys for fun.
So even though she is legally an adult (and most 18 year olds fall into this) she isn't an adult in her maturity (and I don't think she wants to be).
And I am joking about PG 13 thing. Just watching your baby walking into the courthouse all by herself....doing such a grown up thing.
