Crap day at work
The crappest of crap days, in fact; the crappest ever. I let my standards slip not once, but twice, and as a result I caused stress and aggravation not only for myself, but for two of my colleagues, a manager on the other end of a 'phone - oh, and the clients, too. All it would've taken was a little more care in checking that the program I was about to run was going to do what it was supposed to - not wipe out a lot more records than it was supposed to.
