I AM an introvert, and shy, and socially inept! That's three reasons why I enjoy forums like this one where you don't have to speak face to face.
I am also an artist and go to the occasional art opening. I'm the one in the milling, chatting crowd who goes around along the walls, looking at the art, grabs a cookie or 2 and leaves to go home where I can be happily alone.
Surprisingly (to me) I can give talks to a crowd, and sing in front of an audience with no problems, but ask me to chat one-on-one and my brain siezes up.
