I think it makes perfect sense that people just have different tendencies. There are advantages to having different types of people. Even some apparent disadvantages--like near-sightedness, for instance--can also be advantageous. I used to be in the engraving business, making various plates for foil stamping and embossing greeting cards etc. For fine work my Dad needed a lens for, I just took off my glasses. There's a story, maybe apocryphal, but probably some truth to, that Eric Clapton pretty much locked himself in his room for a year and came out a guitar god...

Even going beyond introverts to true social phobics and downright paranoid schizo-spectrum types like me there might be advantages for survival, sometimes the people around you really do suck, and phobia is the appropriate response.

I just think that just as sometimes anorexics will show up on a diet forum looking for support, sometimes social phobics will take the introvert ball and sort of run with it. I think I'd sort of draw the line between I'd rather be in my kitchen alone and I'm scared to be in the kitchen if somebody else is in there.

I need my friend time (looking forward to a get together soon, matter of fact) but my creative time has to be solitary.
