Spent most of this saturday grading exams. Curiously I ended up finishing this task earlier than I thought. Probably it's just a matter of a good time management although I would say it was just pure luck! I usually see myself as a lousy time manager as I get dispersed very easily! Well, at least this time I didn't. (and I'm not taking into account the time it took to write this post)

by the way, do you know where does this clock keeps his time?
