She's gone home now- awful relieved, but slightly confused.
Surely she can't have acted this way purely because she was under our roof!?
Dont her adoptive parents realise what she's doing? Don't they get annoyed with her screaming in the middle of the night and her cutting herself? And what about the drinking!?

She came to hug me and thank me for having her to stay, but i couldn't so much as give her a 'You're welcome'. I did, however, drop in a note about taking care of herself, and laying off the alcohol. She laughed at me.
