Dear David, I'm wr iting to you to tell you how much I like my new school. I iike everything: the teachers, my new friends and the food there. Everybody is very nice and I feel quite at home now. I like our classrooms too. They are nice with large windows, comfortable desks and carpets on the floors. I think our school has got a wonderful name. It's called Halliford School. Our Headmaster's name is John Crook. He is a very nice man and he is also our maths teac her. Halliford School is a private school. Classes begin at 8.50. School is over at 3.55. My friends an d I usually meet at half past eight. I join them in the school yard before classes and we talk, play, sing and laugh a lot. Our lunch time is from 12.40 till 1.50. We study on Monday, Tuesday, Wednesday, Thursday and Friday. We never have classes on Saturday and Sunday.
