I do a lot of work on the phone- answering questions, giving directions, explaining stuff. On a regular basis, I get people... and just there I was interrupted by a colleague that was having trouble with a caller that wasn't listening. It's relentless. The worst ones are the ones that are dead wrong, but insist that everyone else in the world must be wrong or at least broken because THEY couldn't possibly be mistaken. And then it turns out they just weren't listening when they were told the right thing the first time. But of course they don't say "thank you" or "sorry". No, they just huff it off like it was my fault all along that they were stupid. Well, I have a cure for stupid, it's a long walk on a short dock.
