Finally, James said, "Hey, is that a game in your bag?" and we settled down with "Robin" to play a game of Modern Art (breaking in my copy, as a matter of fact). Final score was 523-456-423, which I thought was quite good considering we didn't know how to play and were just figuring it out from the rules.
Even better than the game was the company. James was really nice (he's going to be a daddy any hour now - or day), and Robin and I totally hit it off - I'm supposed to invite her and her husband over for tacos, games, and a tequila tasting session. All in all, it was a very good night!
