Several times each year the Queen gives afternoon tea parties at which guests are served tiny cakes filled with cream from her own cows. Cakes and sandwiches are bought in by footmen, yet you never see the Queen touch a thing. She simply sits beside a big silver plate, pouring cups of tea for everyone and carefully avoiding the cakes.
At cocktail parties the Queen moves from group to group, chatting informally, and manages to make one glass of diet drink to last a whole evening. Tours abroad are difficult because hosts seem to believe the warmth of their welcome must be shown with wonderful state banquets(宴). But the Queen has perfected the art of appearing to enjoy her meal without actually eating much. During one visit to the Pacific islands of Tonga, a specially-prepared dinner was set up in a hut made of wood and bamboo leaves. Deep holes were dug in the ground, filled with hot stones and baby pigs, and the pigs were slowly cooked with dry heat over several days. The Queen looked uneasily at her plate when she discovered a whole roast(烤) pig was her serving.
Then she became uneasy when a turkey, some meat, bananas and an apple were also carried in for each guest. So she depended on her old favourite trick of talking with her host, King Tupou IV, carrying on a warm conversation. At the same time she pushed her food around her plate and only ate a piece of turkey and some fruit.
Reporters traveling with her have noticed that the Queen will sometimes seem so interested in a foreign leader’s political(政治的) chat that she simply never has time to finish a meal before it is time to get up and make her speech. She will lift her fork, then put it down again to make another point, leaving almost all of her meal untouched.
