This is why I hate to get into small talk with someone I've just met. One of the first polite questions I get is "so, what do you do?" and to judge by reactions its as if I immediately start talking like the adults in a "Peanuts" cartoon. And even if I try to be as nontechnical as possible ("I do website work") you can see they just don't want to continue the conversation at that point.
"Yeah, it's almost exactly that exciting. So what do you do?"
