Dear Mr/Ms ..., I'm not feeling very well today. I've got a bad cold. My father took me to see a doctor this morning, and the doctor looked me over carefully and gave me some medicine. He also advised me to stay in bed for a day. So I can't go to school today. I hope I'll get well soon and go to school tomorrow morning. Thanks. Your student xxx
