tl:dr Any specific advice for gaming at a dinner party?

Body:

I'm going to a Christmas dinner party. It is for a sports club and my wife isn't going to attend. I think this is a good opportunity to practice game, because it is a female dominated sport (think yoga, although it isn't) and most people going are females. I'm a foreigner and on average perhaps 15 years older than most people on the club so this party is a bit out of my comfort zone.

Even though I'm an introvert I would like to have fun at this event, and pick up some experience to improve my game.

I'm a rookie at game and most of the advice I can find on the web is based on clubbing scenarios or day game, so even though game is fungible I could use specific advice.
