I think there's a subset condition of NT-ness that I've found an inexpensive treatment for!
"Do you find yourself obsessed with every little detail of other people's social status? Do you ask people all about their job status, dating status, education, what vacations they go on, what they eat, how much their pets cost, what car they drive, where they live/their house, what technology they have, and any other possessions in rapid-fire succession upon meeting them with little regard to their actual personality or being a human being? Do you find yourself making comments on any little feature of a person's appearance that comes within your eyesight range, even including people walking down the hallway not paying attention to you? Do this compulsion occur to you in inappropriate places, like church, towards underlings at a job, or while you're working at a charity?"
"It's a very sad epidemic that sufferers don't seem to recognize, yet leads to misery to those around them. However, if you come across one of these people (and you certainly will, so get prepared!), there is a new solution that provides hope! It's quite inexpensive, and can purchased at places like Wal-Mart, Target, or even the dollar store!"
This new psychological treatment is called................. DUCT TAPE! Simply purchase a roll, cut a piece off about the length of the sufferer's mouth (scissors may be required, and tape measure might be helpful), and place firmly over the lips, smoothing it down firmly. If done properly, their silence may last up to a few hours!
Symptoms may possibly reduce after a few uses, but vocal noises may still occur at first. Miraculous as this is, this may be only a maintenance program. Severe cases needing a cure can require up to a full removal of the voice box.
