I agree with the above post except for one point. When you work at a company and your primary job is working on a PC (doing spreadsheets, documents, etc.) I think the using should learn at least the basics. Such as copying files and installing programs.

Anyway my dumb user story is one day a got a call from a user saying there computer was broken and they couldn't see anything on the screen. Asked if the PC was turned on and they said yes. I thought about it for a second and relizing the person wasn't the brightest monkey in the barrel I asked if they had turned the monitor on. "I don't understand" they said. I said have you pressed the round button in the lower right hand corner of the monitor. After a few second pause I heard the sound of the monitor coming to life in the background. "Oh, its working now, thank you very much. I didn't know they could do that". Just just hung up shaking my head.
