Regarding the OP, sorry, wonkavision's hawtness can be so damn distracting those who know me best think I am some kind of recluse freak of nature, (though as of late they've been changing their minds about that ).
But when I am with acquaintances, I appear quite extroverted.
I would bet strangers find me quite extroverted as well.
When people seem open and receptive to it, (and vice versa), I approach and engage them in conversation.
If I am in the right mood, and you need me to fill the void by talking, I'll do so, and if you need me to fill the void by listening, I'll do that too.
Despite being so energetic and full of life and vocal, in general, there is nothing better than feeling the rapture of admiring someone or something else that is beautiful.
Sure I can talk, but I'd much rather listen, especially if you've got a good story to tell.
