Dealing with end-users or simply beginners is not always a pleasant and easy experience for tech jerks. I personally sometimes get irritated when I have to explain for a thousandth time a simple concept I have already clarified in layman's terms a day or two ago. While I was working as Technical Support and I dealt with users all the time, one of the intricacies of helping people over the phone or via e-mail was the lack of picture – if only I could show them what I wanted, or see what was on their screen, then it would have been much easier to find the problem and solve it.
