One of my classes comprises a lot of sweet but not particularly academic 16/17/18-year-olds and a couple of wise guys plus their acolytes. There's also a slightly plump, hen-toed boy. He has a haircut that looks as if his mum has put a saucepan on his head and hacked away vaguely with her nail scissors; rather old-fashioned glasses; and a lisp.
You probably had someone a bit like this in your class at school. We did, though she was a girl.
The other day he was walking in the college grounds with a friend who was randomly set upon by some youths (not our students). My student bravely tried to help and as a result his glasses were broken and he's now sporting a black eye and a bruised cheek.
Which is terrible, of course. But a welcome side-effect is that he's now seen as rather a hero by the rest of the class, even by the smart-alecs. And the college has paid for some new, cool specs.
And no, we didn't fasten the cats together by their collars.
