21 January 1999.
Mr. Daniel Carter,
Dear Mr. Carter,
I am writing to you to inform to you that I may not be able to attend office for a week from now i.e., from 21 January to 27 January, as I am down with flu. I have been advised by the doctor to take plenty of bed rest for faster recovery. I regret the inconvenience caused to the firm because of my illness.
However I am glad I could meet the deadline set to me for the report of Handles Agency. I have sent it to you for your approval. I am willing to put in extra efforts to reimburse the delay at work once I am back from my sick leave.
Thanks and regards,
