If only proximity had something to do with it.
I get calls from the UK from my family asking how to fix things. Well, they're my family, they've had to put up with me so they should get something in return after all. They're also good enough to say what it was they were doing at the time and exactly what the error message was.
But some people (I'll call them 'friends' and 'neighbours' and 'inlaws') who just call me then start a stream of conciousness and expect me to do something about it, as if I could tell them how to remove a rootkit after being told 'Firefox just opens then it closes, but Internet Explorer works although it crashes sometimes and a virus message comes up every minute. No, I didn't disconnect my computer from the Internet when you asked me to, why?'
