Someone who is always making excuses, but all excuses seem to be irrational, or easily proved wrong on the basic premise of the excuse itself.
I assign a new user to a system, then when they can't access the system, I see that the password I issued has a double S instead of one S. Being irrationallyexcusive, I blame the keyboard for adding the additional S to the password.
