The Small World Phenomenon

Wonder if you have heard of the Six Degree of separation theory...

It's about how people are all interconnected in a circle of friends where friends of friends know other friends who happen to know some other friends and eventually it become a circle when the some other friends know that first friend.

Right.. I am making this complicated. Anyway, just to encapsulate it all, the theory suggests that people are all acquainted in such a way that it will never be more than 6 people.

Have it ever occur to you? When there is someone you have seen and never got to know them but just to realize that they are actually acquainted to you through some friends' friends.

Still, it does take a little fate to know them. Isn't it?
