Dear Mr．Johnson，
Please excuse my absence from school today．I coughed a lot and had a high fever last night．This morning those terrible symptoms are still killing me， even worse than yesterday. So I met the doctor this morning and he said I have got a flu and need to rest for several days. So I am writing to you to ask for three days" sick leave and I promise I will be back to school as long as I feel better.
