      Girls wore grey skirts and white shirts, boys wore grey trousers, and everyone wore the school tie.
Some of Sam's lessons were a bit strange for me. We were reading Shakespeare in the English lesson,
and there were quite some old words like "thou" and "thee" to mean "you". In history we studied 20th
Century China. It was strange hearing a foreign side of history-and hearing English people trying to say
all our Chinese names!
      Classes were also a lot more relaxed than in China. Teachers were called "sir" or "miss", everyone
shouted answers and raised their hands in classes. It was more like a debate than a class. A bell rang
at the end of each lesson and everyone jumped up to go to the next class.
     At break we bought potato chips and cookies in the dining room. Lunch was later than in China-at
1 o'clock. We had big plates of pie with carrots. For dessert there was hot sweet rice called rice
pudding. It was good that I'd had an excellent lunch, because at Sam's school Monday afternoons are
taken up with sports.
     I played my first game of netball-a bit like basketball, but with some differences. Luckily I'd had a
quick look in the rule book before I tried to join in the game.
