I feel I should explain yesterday's outburst

Basically, nothing in my project is working, at all, even simple stuff like restriction digests.

Also, I've managed to lose an expensive text book, and I'm double booked for tonight by the fencers and some of my friends, so I'm starting with the fencers and then moving on to my friends except, despite the fact that they drink more than me, that bunch of friends can't take their alcohol and I hate being the sober(ish) one.
