Dear ...(имя кому пишешь),
Thank you for your letter. It was nice to hear from you. In your last letter you ask me about food. As for me, I don't like fast - food because it's not healthy food, and big lines...it's very bore. I like fruit and vegetables, most especially fruit salat with strawberry and pineapple. But, I'm a student, and sometimes fast - food help me. Because I eat 3 times a week, and in lunch I'm not at home. Sorry, I need to stop now.
Keep in touch,
...(твоё имя)
