It's often been my comment that when I'm at a table of three, I watch the other two talk to each other.
I'm an introvert, you see. (Loyal readers [which don't even include my mother, by the way] already know this.)
My comment isn't entirely accurate, though. I do talk a little bit. Recently I've started constructing a mathematical expression for my relative loquaciousness. Some observations:

If I'm with one person, I talk 1/3 of the time. (Ladies, are you paying attention?)

If I'm with two other people, I talk 1/6 of the time.

If I'm with three other people, I talk hardly at all. I'm comfortable in assuming that I talk 1/12 of the time.
A geometric series presents itself. (apologies for my blogware's ineffectiveness at mathematical expressions)
Let n be the number of people at table (including myself)
Then x is the fraction of time I speak at table:
x = (1/3) * (1/2)^(n2)
One implication of this equation is that when I'm alone, I talk only 2/3 of the time. That's about right. The voices in my head get the other third.
So, where I need help:
I need one person to talk to to keep the voices in my head silent. In exchange, I'll listen 2/3 of the time. Bonus points if you're attractive. (LOL.)
