It's not as bad as I feared (which was diabolically bad).
But I cannot understand why people would write this, for example, (and others would unquestioning pass this on as sensible advice):
So, the young person has decided that they are exhausted and shown the teacher the timeout card. They have walked to the quiet space e.g. the library, which may well be in another block or up some stairs, settled themselves down to sort of relax, and then five minutes later, it's expected that they will be getting up to walk back to the classroom? The chances of that regime having any sort of positive outcome is very slim indeed.
