Dear Jim,
Thank you for your letter. I was so happy to get it! I would like to have more letters from you.
Firstly, I want to say you, that I often miss school, because I have health problems once or twice a month. I don't know why and I think it's bad!
If we talk about how I entertain myself when I am ill, I watch TV, play computer games and sleep a lot, because it is very good for my health.
