Well it looks as though the consensus is to hook up with some of those AA folks after meetings.
Tyates I can assure you that if you go to a newcomers meeting or a same sex meeting you will find that you are not alone in your being introverted, that at least one person there wishes someone would say something as simple as "Hey you want to hang out for a while after the meeting?" Some one has to break the ice, go early and help set up, stay late and help clean up. I garauntee at a minimum a conversation will be struck up.
