...as Tommy Cooper could've said, but probably didn't.
At the Centre, we have a wide variety of students with an equally wide variety of problems. Some just haven't fared well in mainstream; some have had too many family issues to deal with too young; some have specific learning difficulties; some have mental health problems. Bearing the latter in mind, it was probably unwise of me to murmur "nutter!" affectionately at one young lad -a lad I like a lot - when he said something funny and unexpected.
I realised about half a second too late that he'd been referred that very morning to the local mental health facility, and stuttered a retraction gormlessly while he grinned at me.
