Dear Teacher,
I'm sorry I have to trouble you. But I really need to have a day off. After school yesterday afternoon, I felt terrible. My father took me to see the doctor. The doctor looked me over. He said I had a bad cold and really needed to have a good rest. I know we'll have the mid-term test soon. I'm worrying my studies. I hope you can agree with me. I'll go back to school as soon as I feel better. Thank you!
