WASPs love dinner parties and lawn parties, or in other words, reasons to drink Scotch or G&Ts. It amazes me how areas like the dining room are synagogues for gossip or areas for high class espionage. Mistresses are born here, and deals are made over a casual after dinner smoke.
I can also say that I enjoy these occasions as well, and I attended one this past week. At this party, we discussed politics (who slept with who in D.C), pipe smoking, and classic clothing. So, if you want to be indoctrinated in WASP culture, get an invite to a dinner party and observe.
