Well, I do believe that social functions involve the spiritual, mental, and a certian amount of physical. Mostly the spiritual, though -- I was thinking of Creativity having something to do with how well you pick up on other people's emotional state, Passion with how well you can influence other people, Fortitude with how well you can keep your own counsel, resist being pushed around, and so forth.

But, for me, it seems that the initial impression people get of someone is based on their force of personality, their physical presence, and their mental quickness. And I believe that convincing people of things involves a certain amount of logical argument -- although more involved with the spiritual ability to understand people, which is why it could be based on Creativity, to understand where people are, Reason, to work out a route from where they are to where you want them to be, and Passion, to drag them along your route with you.
