school the other day. It was very strict, and if
they didn't wear a uniform they had to go
home and change their clothes. Students got
for things like not sitting
properly in class. He said he often had to
usually 'I must not talk
in class'. There were physical punishments,
too, if you didn't arrive 4
for
school, or
in an exam. Even
if a teacher heard you
you had to go and see the principal. He also
said there was a lot of 7
but no-one told the teachers. What about
rewards? I asked. He said the students who
always handed in
the next
day and got
9
in their exams
sometimes got a boring book at the end of
the year. His school was very different from
ours!
