I've been so busy recently that I couldn't find the time to write a proper good-bye here. I know you understand me because you've been running around with much the same symptoms: rushing back and forth, forgetting stuff, with eyes wide and wild, desperate at times... But at least the classes are over, so now we can start dealing with things that have been waiting patiently for weeks.
Anyway, in this hasty mode I would like to thank you all for this year together, and for keeping high spirits in class most of the time. I enjoyed working with you.
Good luck in your work, studies, family life or anything else you have made plans for. I'm sure you can do a lot of interesting, useful things. Take care! :)
