I'm sexier in real life.
Okay, I'm probably about the same, but I think I hold back a little on greekchat -- for the same reason mentioned above, that I'm really presenting myself here as an Alpha Phi. There are things I'd discuss freely in real life that I probably wouldn't here, for that reason -- I'm talking more personal things/experiences that I'd share with my friends. I have a whole wild & crazy life out there...
Other than that, I'm the same. I tend to be pretty opinionated and outspoken and often my emotion gets the better of me and usually wins out over hard logic.
