MORE ON HANDSHAKES -- "BUT I'M INTROVERTED!"
I thought one of the central things we believed as Catholics is that our psychological make-up is not our destiny. We have the ability, with the help of God, to rise above our perceived limitations, and do things we didn't think we could do.
You know what I'm introverted, too. I'm about a 90 on the scale for "I." I hate small talk, and am uncomfortable at parties. But I can still somehow manage to make herculean effort to stick my hand out and say my name to the folks sitting next to me.
Come on -- being introverted is a tendency, not destiny. There's a time when extroverts need to be quiet, and there's a time when introverts need to speak up.
