Dear XXX
I need to ask for one day leave.The reason is that I played a football match yesterday and got wet all over after the match.I took of my sweater and went home with only a T-shirt.This morning,I got a fever,a headache and sore throat,I went to a doctor and the he recommended me to take the pills and have a good rest.I will try to go to school tomorrow.I am looking forward to your kind approval.Thank you very much!
