当你无条件地去爱时，不是因为你爱的人是完美的，而是因为你学会完美地看待一个不完美的人。

When you love unconditionally, it isn't because the person you love is perfect, it's because you learn to see an imperfect person perfectly.

因为别人从未告诉你你是完美的，你觉得自己毫不完美。

You feel less than perfect because you have been told by others that you are not.

What is this? This is a wonderful piece of abstraction. It is saying, you don't need to know squat about what's inside the body of this function. You don't have to worry about the parameter names, because they're going to be preserved, you don't need to worry about how I'm doing it, this tells you how you can use this, in order to use it correctly. Of course, I can then close it off, and off we go.

但是这能告诉你一些信息,这是什么？,这是一段完美的抽象,它的意思是你不需要知道,这个函数的内部构造，你不必担心参数是否重名，因为它们已经被预存了,你不需要担心我如何使用它,它告诉了你你该如何操作，从而正确的使用它，当然我也可以把它关掉。
