I'm writing to you to tell you how much I like my new school, I like 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 teacher. Halliford School is a private school. Classes begin at 8.50. School is over at 3.55. Myfriends and 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 and Friday. We never have classes on Saturday and Sunday.
There are many subjects on our timetable. They are: English, Maths, History, Geography, Handicrafts, P. E., Music, Arts, Computing. I think they all are very interesting and very important. We have three terms: Autumn term, Spring term and Summer term.
We usually wear uniforms at our school. It is a navy blue blazer with the school badge on it, grey trousers, a grey or a white shirt, grey socks, black shoes and a tie. When it is cold we wear pullovers and coats. I have a special uniform for my football and P. E. classes. I'm sending my school rules to you. We don't have many, but those which we have I think are very important.
We must wear uniforms and not be late for school and classes. We must have pens, pencils, rulers, rubbers, exercise-books, our diaries and all the necessary books for our class. We must hand in our homework on time. We mustn't smoke at school, and if we have bicycles, we must keep them in a good state of repair and we must behave at all times with courtesy, consideration and common sense, which is not always easy you understand.
But I'm sure my life here will be more interesting than it was in my primary school. I am older too. I am twelve now. We spend much time outdoors. Sometimes our teachers take us to famous museums and other interesting places in London. Our teachers often say that pupils at school are not only to learn the lessons and work (usually in the classrooms, practical rooms or laboratories, on the sports grounds) but to learn how to get on with other pupils and other members of the school who look after us and the school. We learn how to live together with people of different ages.
That's all for the moment. Write to me as soon you can.
Hope to see you at Christmas.
