| Teacher to students:
"I'm afraid I haven't got enough copies of this exercise.
I tried to have more run but the photocopier
had broken and the repairman
didn't turn when he was supposed to.
He did ring to say he'd been
held unexpectedly, but that's the second
time that company has let us recently.
Well, there's nothing else for it: you're just going to have
to look with your neighbour. While you're doing
that, I'll just give the test you did last week.
Some of you slipped in a few places,
but, on the whole, the results were good. If you
carry as you've been doing, you should do fine!"
