She's simply too strange. We can't relate to her, she speaks in a funny way, she comes from an odd place. So we can't relate to her, and when you can't relate to somebody, you don't envy them. The closer two people are -- in age, in background, in the process of identification -- the more there's a danger of envy, which is incidentally why none of you should ever go to a school reunion, because there is no stronger reference point than people one was at school with.

她太怪了，我们无法想象自己与她扯上关系，她的语调令人发噱，来自一个奇怪的地方，我们与她毫无关联。当你认为你与这个人毫无关联时，你便不会嫉妒。越是两个年龄、背景相近的人，越容易陷入嫉妒的苦海，所以千万避免去参加同学会。因为没有比同学，更强烈的参照点了。
