@some of the above
Whatever we call it - those that have it, are clearly gifted and just get on with it. Those that don't know what we're talking about, are either lusers or bosses.
Case in point:
User: My laptop won't open a web page.
Me: Are you connected to the network/modem?
User: Yes, I haven't unplugged anything since yesterday and it was working then.
Me: [presses wireless 'on' button] There..... try it now.
User: [click] It's working. What did you do?
Me: I pressed that button [points at wireless on/off button] and turned the blue light back on. That's why it wasn't working.
User: Oh, I turned that off last night, it was bright and annoying. Can't it work without a blue light?
Me: [muttering x%^$%*£ under my breath, grinds teeth]
And yes, he was a very successful, well-paid manager. I'm sure we've all been there.....
