They are waiting in line at a bagel
shop
Wei: Did you know that
Uygur people in western China have bagels?
Paul: I thought bagels came from Eastern European
Jews.
Wei: Maybe they invented them separately.
Paul: Do the, uhhh, Uygurs, boil their
dough before baking it?
Wei: I'm not sure how they make them, but they have the same
shape.

cheese in China, too.

他们在贝果店排队
小薇：你知道中国西部的维吾尔族有贝果吗？
保罗：我以为贝果是来自东欧犹太人。
小薇：也许他们各自发明了贝果。
保罗：那，呃，维吾尔族在烤贝果前会先把面团煮过吗？
小薇：我不确定他们是怎么做的，但两种贝果的形状都一样。
保罗：别告诉我中国也有熏鲑鱼及奶油起司。
小薇：没有啦，是西红柿和羊奶之类的东西。

Now I must stress the importance of finding a common language.
By that I don't mean English, Chinese, German, French, etc. I mean
finding something you have in common with another person on a
spiritual and philosophical19 level: likes, dislikes, worldviews,
ways of thinking, and attitudes toward life. And to start, you must
first enhance your knowledge of the particular culture from which
your potential new friend comes from.
我必须强调找一共同语言的重要性。我指的并不是通常意义上的英、中、德、法等语言。我说的是寻找你与他人在精神方面和人生哲学方面的共同点：喜欢什么、不喜欢什么、世界观、思维方式以及对生活的态度。开始时，你必须首先加强对你想与之交朋友那人的文化背景的了解。
