Re: Late Assignment
I regret to report that due to an extremely full calendar these past two weeks I will be unable to hand in the assignment on time.  I am sure that you appreciate the pressure I have been under and, since you have nothing to do but sit in your office anyway, I feel certain that you will accept my assignment whenever I get around to handing it in. If there are any problems, please leave a message on my answering machine.

Thank you,
Becky
