CAROL AND BOB: They’re the fun-loving couple that never misses an opportunity to party, even if it means listening to classical music rather than Jimmy Buffett. Bob, in the Hawaiian shirt and ponytail, has brought two coolers loaded with wine. Carol, in a tank top and shorts that have seen better days, breaks out the Cool Ranch Doritos. Those sitting around the rambunctious couple are annoyed at first when they start tossing around a beach ball, but quell judgment when Bob graciously starts passing around cups of wine.
