Stop in for a cup of coffee

Very true, but it is true as well.

I just want her to be a responsible young adult and she isnt being that person yet... I have to let her figure it out, I just have to figure out how.
Honestly, this is a crazy idea but try letting her stand on her own 2 feet. IE sit her down and let her make up her own rules for herself within reason of course and then come to an understanding of the consequences of failing to meet those rules.

like I said, crazy idea but who knows
