Subject: note for sick leave
Dear Mr. James Zhao,
I would like to know if I could ask for a sick leave for one day on March 29th.
I just caught a cold, then I hope I can go to hospital that day. And I will try my best to finish my work on March 28th.
Many thanks. I'm looking forward to your kind answer.
