Dear Masha,

My first days at school were awful. The house is a ruin. We are in a big old room with no central heating. It is really cold. I have to wear a stupid uniform. I hate it! We get up at seven, and there are nine lessons every day! The teachers are very strict. We can only speak to them if they speak to us. We must call them Sir or Mrs.

Yesterday when I was running in the corridor, Mrs Nasty saw me. I got a detention for this. I had to stay in her room after school and do lines. I wrote "I mustn't run in the corridor" two hundred times. I think Mrs Nasty hates me.

We can choose some optional subjects, but Maths, English, English Literature, one foreign language, Religious Education, IT, DT, one subject from the arts and one subject from the sciences are compulsory.

I don't like the other boys from my class. They are nice and polite when the teacher is there, but when the teacher isn't there, they are really cheeky. At the moment I don't have any problems with them, but they bully Rob. I feel really unhappy and homesick. What can I do?

Much love,
Misha
