LOL. That's how they show their true colors, by getting mad that I insulted their intelligence.

P.S.
I have worked with a homeless woman who really didn't have the skills to use the Internet on her Obama phone, and she was truly appreciative that I showed her. I consider this homeless woman to be a very smart person, because she is smart enough to pursue skills that she needs, and not waste her time or my time by pretending not to know something she already knows.
