An amusing theory

An amusing theory came up in my mind these days .We all know that a lot of people describe the globe as a small village . So I won't be too surprise if I ran into a friend that I haven't met for a long time .And that comes the question . What will I react at that moment ? Will I just say hello , or I’ll pretend we don't know each other at all and just walk away. I hope I can be a person who is not a afraid of talking to someone I know but also people I don't know at all . And I'm glad that I have figure out this for quite awhile . Because in this society which is full of people , we really need to stand out from the crowd .
