poor you, and what a horrid day all in all.
I have no experience of teenagers, but it does strike me that she is awfully young for the responsibility that she is giving herself, ie weekends away with boyfriend, travelling by herself.
My mother used to steal stuff from her mother's purse at about the same age, in the 1940s, and she grew out of it.
What would happen if you upped her pocket money, and told her that you expected her to live up to it by behaving like an adult?
Is she starting the bac this year, and might that give her a new direction?
