Well, if you ask me, I will tell you that I am the most agreeable person in the world.

It's just that usually most people suck at making a convincing argument not based on their prejudices/personal anecdotal experience etc So, typically I end up disagreeing. XD

As for the introvert/extrovert thing, I think I always had a nice balance. I can have fun both with myself and with company... Hmmm, that didn't sound as I wanted it to, but oh well, it's still true XD
