表达人生聚散离合本是常态，不必在分别时过于伤感

人心比万物都诡诈，坏到极处，谁能识透呢？

I will hazard a prediction. When you are 80 years old， and in a quiet moment of reflection narrating for only yourself the most personal version of your life story， the telling that will be most compact and meaningful will be the series of choices you have made. In the end， we are our choices. Build yourself a great story.

常识就是人到十八岁为止所累积的各种偏见。
