Sleeping Time

I received this email yesterday afternoon:

Dear Michelle,

I please you to excuse me for the past session last Thursday, that day, my time of sleeping overlapped with the session time.

Please write whether that is OK.
Sincerely,
George [Names have been changed to protect the not-so-innocent]

What do you think? How would you write back? Like the following?

Dear George,

Of course you're excused for missing my class last Thursday. I find that the class time overlaps with my sleeping time too, so please excuse me when I do not show up to teach class for the rest of the semester.

Sincerely,
Michelle

P.S. You're still expected to do all of the assigned work as outlined on the online syllabus. Please let the class know.
