Yep I remember the old lets take the car an not bring it back trick. AD seemed to do that more when she was using crack than when she was heroin. My husband had a hard time realizing his daughter is an addict. He always said she was young an doing stupid things, an that he hoped she'd grow up before she got killed.
It's so hard being a parent of an addict you love them an don't want to turn your back on them, yet you have to let them fall. Sending prayers for you an your family.
