I have seen this situation somewhere before:
All right, settle down, settle down.
Now before I begin the lesson will those of you
who are playing in the match this afternoon move your clothes
down on to the lower peg immediately after lunch before you
write your letter home, if you're not getting your hair cut,
unless you've got a younger brother who is going out this
weekend as the guest of another boy, in which case collect his
note before lunch, put it in your letter after you've had your
hair cut, and make sure he moves your clothes down onto the
lower peg for you
