Happy birthday, sis! Although you can’t rewind and get any younger, at least we can stop counting from this year onwards to make sure you don’t get any older!
I think that for your birthday this year, you should postpone all homework and any planned exams for a while…
I mean, surely you don’t want to be grading papers around your birthday!
You should just relax and not worry about setting any work that’s too taxing or strenuous! I’ve checked with my fellow classmates and none of us mind at all!
Enjoy your relaxing and stress-free birthday this year, teach!
