My favorite simultaneous action is talking while eating. I think it's a sign of class. The rich have many advantages over the poor, but the most important one, as far as I'm concerned, is knowing how to talk and eat at the same time. I think they learn it in finishing school. It's very important if you go out to dinner a lot. At dinner you're expected to eat—because if you don't it's an insult to the hostess—and you're expected to talk—because if you don't it's an insult to the other guests. The rich somehow manage to work it out but I just can't do it. They are never caught with an open mouth full of food but that's what happens to me. It's always my turn to talk just when I've filled my mouth with mashed potatoes. The rich, on the other hand, seem to take turns automatically; one talks while the other chews; then one chews while the other talks. If for some reason the conversation demands an immediate comment in the middle of chewing, the rich know how to quickly hide the half-chewed food somewhere—under the tongue? behind the teeth? halfway down the throat?— while they make their point. When I ask my rich friends how they do it, they say, "Do what?" That's how much they take it for granted. I practice at home in front of the mirror and over the phone. In the meantime, until I've perfected the ability to talk and eat simultaneously, I stick to my basic rule for dinner party behavior: don't talk and don't eat.
