It's 9.30 pm here and I plan to go to bed before long. However, I want to make sure I have responded to every assignment you sent.
With the nestled threads, it's likely that I've missed someone. If you haven't received a reply to your assignment, can you please give me a shout? Then I'll reply before I go to bed.
I think I've caught up with all the assignments that have been handed in. I would offer to continue tomorrow, but tomorrow my month-long seminar starts, and I'm committed to give all my time and attention to it.
If I still owe you a reply and we can't communicate before the end of the day, or if your weekend is over long after mine - time zone differences being what they are - then contact me by email: firstname.lastname@example.org.
I don't want to let anyone down!
