The rest tend to trigger such thoughts as, Why did I wear such unfortable shoes? But graduation speeches are less about the message than the messenger. Every year a few colleges and universities in the US attract attention because they39。ve managed to book highprofile speakers. And, every year, the media report some of these speakers39。 wise remarks. Last month, the following words of wisdom were spread: You really haven39。t pleted the circle of success unless you can help somebody else move forward. (Oprah Winfrey, Duke University). There is no way to stop change。 change will e. Go out and give us a future worthy of the world we all wish to create together. (Hillary Clinton, New York University). 39。This really is your moment. History is yours to bend. (Joe Biden, Wake Forest University). Of course, the real get of the graduation season was first lady Michelle Obama39。s appearance at the University of California, Merced. Remember that you are blessed, she told the class of 2009, Remember that in exchange for those blessings, you must give something back... As advocate and activist Marian Wright Edelman says, 39。Service is the rent we pay for living ... it is the true measure, the only measure of success39。. Calls to service have a long, rich tradition in these speeches. However, it is possible for a graduation speech to go beyond cliche and say something truly pelling. The late writer David Foster Wallace39。s 2005 graduation speech at Kenyon College in Ohio talked about how to truly care about other people. It gained something of a cult after it was widely circulated on the Internet. Apple Computer CEO Steve Jobs39。 address at Stanford University that year, in which he talked about death, is also considered one of the best in recent memory. But when you39。re sitting in the hot sun, fidgety and freaked out, do you really want to be lectured about the big stuff?. Isn39。t that like trying to maintain a smile at your wedding reception while some relative gives a toast that amounts to marriage is hard work? You know he39。s right。 you just don39。t want to think about it at that particular moment. In fact, as is the case in many major life moments, you can39。t really manage to think beyond the blisters your new shoes are causing. That may seem anticlimactic. But it also gets to the heart of one of life39。s greatest, saddest truths: that our most memorable occasions may elicit the fewest memories. It39。s probably not something most graduation speakers would say, but it39。s one of the first lessons of growing up.91.

For example, in some societies, the nuclear family is the unit that regularly eats together. The anthropologist Mary Douglas has pointed out that, for the English, the kind of meal and the kind of food that is served relate to the kinds of social links between people who are eating together. She distinguishes between regular meals, Sunday meals when relatives may e, and cocktail parties for acquaintances. The food served symbolizes the occasion and reflects who is present. For example, only snacks are served at a cocktail party. It would be inappropriate to serve a steakorhamburgers. The distinctions among cocktails, regular meals, and special dinners mark the social boundaries between those guests who are invited for drinks, those who are invited to dinner, and those who e to a family meal. In this example, the type of food symbolizes the category of guest and with whom it is eaten. In some New Guinea societies, the nuclear family is not the unit that eats together. The men take their meals in a men39。s house, separately from their wives and children. Women prepare and eat their food in their own houses and take the husband39。s portion to the men39。s house. The women eat with their children in their own houses. This pattern is also widespread among Near Eastern societies. Eating is a metaphor that is sometimes used to signify marriage. In many New Guinea societies, like that of the Lesu on the island of New Ireland in the Pacific and that of t
