Dear Tim,
I was glad to get your letter.I’m sorry I haven’t answered earlier but I was really busy with my school.You asked me about my school.I study at school number seven. My school is a three-storeyed building with a lot of classrooms, where we learn different subjects.Our school has two gymnasiums with all the necessary equipment. We often stay there after classes and play volleyball. Different sports competitions are held there.
And what about your school?How many floors there ?
Anyway, I have to go now because my Mum asked me to help her with the washing up.
Hope to hear from you soon.
With best wishes, ну и свое имя напиши)

Hi, my friend, how are you? I`m fun.
P.S.- а дальше я не понимаю кому писать, ибо pen это ручка..и другу ручке?
