I'm suprised that i didn't post in here earlier, considering how
I have this same character as you.
But then again, think about it. When you are one-to-one, of course
the chances of you speaking up increases significantly. Because its
either u start talking or the other person start talking.
When in a big group, somehow, people tend to be more cautious,
because u do not want to be seen as the one who make decisions, or
speak up. Because when things go wrong, and people start to
finger-point, u will be deemed the culprit.
I think only the ultra-going and hyper ones will tend to be the
ones to speak up in a big group, and be the "life of the party"
