I was shocked and utterly horrified when people started coming to ME for computer (or printer, or photocopier) advice. It cannot be possible that I'm the one they need to ask. I soon learned it's less because I'm "handy" than for one of these two reasons (sometimes both):
"When the printer breaks, emails won't send, the website needs updating or your organisation's newsletter needs designing, do you always end up doing it? Then you're an accidental techie. It's not what you signed up for, it's just that no-one else is as handy as you around computers."
