If You Can't Read, Don't Go To The Library

This man came up to my desk at the library and said that he and his wife had been trying for about 5 minutes and they couldn't get their password to work on their computer. My friend, Carol, was the one who had assigned them their password and computer. She asked me if I would help them. (Mostly because she knew if it was something more technical than a wrong password, she'd have to come and get me anyway!) So, I go over to where they're sitting on computer 1D. They reiterate that they can't get their password to work. I then ask for their reservation slip. With a quick glance I immediately recognize their problem. I kindly ask them to follow me over to computer 1E and then type in their password which, miraculously works. Seriously, if you can't read what are you doing on a computer, let alone one in the library?
