To think I didn't make her homeless?

[Wheyv]

DD's college seem to be quite concerned here and I'm actually really worried now. DD's behaviour was absolutely horrendous, words such as "I wish you were dead" and "you're a cunt" were thrown around and I just couldn't bare to have her here. She refused to stay out of my sight and so I told her to get out, she then said well where am I supposed to go? And I said I didn't care and for her to just get out, she left. It hit around 9pm and it was getting dark, I told elder sister to suggest she could go stay in her flat... eldest sister texted her and said she could go stay there (eldest is visiting) so DD did. DD didn't know it was my suggestion, but I knew she was safe and told the college this. But apparently they're still concerned and were blabbering in about how I have parental responsibility... she is 17 for gods sake! AIBu?

Parental responsibility is 18 but services still recognise anything over 15 and 9 months as old enough to do what they want really, at least that's what they told us a few years ago when we took in my teenager BIL and wanted their help (MIL is an abusive alcoholic drug addict etc). The college are right but by 16 no one enforces it and tbh the college need to keep their beak out. She's 17, likely soon 18, not 12.

Social services really wouldn't class it as abandonment; essentially all that happened was that OP's DD went to stay at her sister's flat for one night before going back home.
