my friend wants to stay in my house despite me being in self isolationWatch
Don’t put yourself and your family at risk for someone who parties during a pandemic.
Who is she supposed to be living with? Parents, foster carers, etc? Why can’t she go there?
If she really can’t go home, tell a teacher at school that your friend has been made homeless. Email or phone them ASAP since you can’t go into school. They can get her the right support.
Is the price of a life of a loved one £50 or even £10,000?
Don't shoulder the responsibility of your friend's carelessness.
OP doesn’t say how old they are.
If she’s a child and is actually going to be homeless, then no, I don’t think it is. I think helping her to not be homeless is the right thing to do.
It's a bit of stretch to jump to that conclusion IMO, and i'm not sure how a school could or would react to a 3rd party pupil asking them to get involved. Going ahead and telling OP to contact them ASAP without any further info feels a bit irresponsible tbh.
If it was reported, the school would follow their safeguarding procedures. It’s not uncommon for a third party to be the one who brings up an issue, whether intentionally or accidentally, e.g. if a teacher overhears a pupil talking about another pupil self harming. (I’ve worked with children in non-school settings, so have done much of the same safeguarding training as teachers have.)
