I'm an introvert at heart, although I'm able to fake it and my friends/colleagues are often surprised to hear that I think of myself as an introvert!

I think there are lots of people like me ("fake extroverts") that can pass for extroverts. It's tiring though and I try to limit my socializing so that I spend most of my time with friends! Luckily my wife is also a fake extrovert, so we're on the same page there.

Any other fake extroverts out there?
