     I hated dinner parties. But I decided to give them another shot because I'm in London. And my friend Mallery invited me. And because dinner parties in London are very different from those in New York,

     "I'm having a dinner party" means: "I'm booking a table for 12 at a restaurant and we'll be sharing the

cheque evenly (平均地), no matter what you eat." In Manhattan there is always someone who leaves

before the bill arrives. They'll throw down cash, half of what they owe, and then people like me, who

don't drink, end up paying even more. But if you try to use the same trick, the hostess will shout: "Where

are you going ?" And I cannot say I have somewhere to go because everyone knows I have nowhere to

go.

     But in London, dinner parties are in people's homes. Not only that, the guests are an interesting mix.

The last time I went to one, the guests were from France, India, Denmark and Nigeria; it was like a

gathering at the United Nations. In New York, the mix is less striking. It's like a gathering at

Bloomingdatle's, a well-known department store.

     For New Yorkers, talking about other parts of the world means Brooklyn and Queens in New York.

But at Mallery's, when I said that I had been to Myanmar recently, people knew where it was, while In

New York people would think it was a usual club.
