Dear all,
I am very sorry for bothering you again, but clearly my proposal was not very reasonable, since on Friday afternoon/evening many of you cannot attend my lessons. From the survey that some of your colleagues conducted for me (and here again my heartfelt thanks to them), it emerged that Wednesday afternoon 3-5pm is the best solution for all of you, instead of Friday 5-7. So, could you please confirm that it is okay for you to have lesson on Monday 9-11am and Wednesday 3-5pm? I know it's so annoying, but it's for the best!
