Grrrr... aaaargh

You know, it's infuriating when you spend your money and time going to an after work seminar on something, only to discover that the person doing it has used a book you already own as the basis of his talk on the subject at hand and essentially has nothing new to add of his own.

That's 3 hours of my life I'll never see again. :(

E.T.A. On the other hand, I did spend a productive 3 hours in the university library doing research for the assignment that's due in Monday, so not all Grrrr and Aaaaaargh, I guess. :)
