Girl in work calls me in a panic to tell me her computer's crashed ('m the only man in the office, so it falls at my feet to sort technical problems), so I wander over to see what the fuss is about.
Me: What happenned?
Girl: I was trying to load up (sic) a CD, and all of a sudden, it just crashed!
Me: Ok. Show me what you did.
Girl (switching computer back on): I just pressed... oh, wow... it's back on now!
Me: Err... yeah, that's what happens when you press the power button.
Girl: But I pressed... oh... err...
(Cue some eye-rolling from yours truly!)
