Introvert 2

"Depending on which study you consult, one third to one half of Americans are introverts—in other words, one out of every two or three people you know. (Given that the United States is among the most extroverted of nations, the number must be at least as high in other parts of the world.) If you’re not an introvert yourself, you are surely raising, managing, married to, or coupled with one. If these statistics surprise you, that’s probably because so many people pretend to be extroverts. Closet introverts pass undetected on playgrounds, in high school locker rooms, and in the corridors of corporate America."
