I wouldn't call today bad, but it certainly wasn't in the good category either. I had to go troubleshoot a customer network, which was something I wasn't in the mood for. That alone put me in a rather sour mood, and it didn't help things that neither I nor the customer had critical information about the network switches. It took about two hours (and that abomination of a program Microsoft provides called Hyperterminal [1]—and in looking up that link, I find that Microsoft didn't even write that abomination [2]) to secure the information that we should have had (and thus, made me angrier, more at myself than at anything else). Two hours wasted getting to a point where I could actually troubleshoot the original problem.
Sigh.
