So, RPG.

Are you an introvert, who likes to Rp because it means that they can pretend to interact with people while not actually being around them?

Are you an extrovert, who Rps because they're so damn addicted to other people that they have to pretend to be different people to get the same fix?

Or are you a real person, who is all along the sociability spectrum? 

I'm curious to know how people's meatspace relationships influence how and why they Rp.
