Excuse me whilst I seethe.
It was 16yo DDs last GCSE this morning at school a couple of villages away. She'd already tried the "School doesn't want us there, says we can't stop there" trick and I'd pointed out that this was bullshit unfortunate and that she would have to wait until 3.30pm to get the school bus home.
So, at 11am she gives me heart palpitations by leaving a "Call me! NOW!" message on 0800 reverse - she's got no credit left for emergencies on her mobile of course. She tells me that she's left school and is walking home (along dangerous A and B roads without pavements). I tell her to get her arse back into school! Madam argues that she doesn't want to be stuck there on her own.
I call the school to confirm that they're happy for her to remain until 3.30pm. Call madam back to say that school suggest the library and use the PCs, you have money, soon it will be lunchtime anyway, it's only 4.5 hours. Nope, she's going to call her father on 0800 reverse (who does sod all and will tell her to piss off). Failing that she's - get this - going to call her friend's Dad, who lives further away than we do and who she knows to be struggling for money, and ask him, as "The two people who should be doing this for me and caring for me won't".
She's right on one of them... but WTF am I supposed to do? Fashion transport for her out of a lawnmower and a few bits of wood? 
Her Prom is very much at risk of going ahead without her on Friday, that's for sure. Otherwise, can I slap her please?
