The Yin and Yang in the film Serendipity 2001: a book and 5 dollars

Some call it Fate some call it Destiny.  You can even call it Luck, Providence, Synchronicity, Fortune, the Force, the Dao or Tao even Murphy's Law.  Certainly there is an immeasurable force in the Universe that binds people, places and things to each other, and plays with the outcome of events.

Know it is good that this force is immeasurable, otherwise science would have turned it into a weapon or toy, and marketing executives would be shoving it into your face to turn a quick profit. 

In the fall of 2001 the film Serendipity became the modern day calling card of this magical uncontainable phenomenon without being too flaky or too serious.  It was in that lustful Goldilocks position, palatable to all types of audiences.

SPOILER ALERT: DO NOT READ UNTIL YOU HAVE WATCHED THE MOVIE AND HAD A BROKEN ROMANTIC HEART

   In the film Sarah attempts to test Fate when she makes Jonathan write his telephone number on a five dollar bill.  She then uses it to purchase Certs breath mints and argues that the five dollar bill with his number on it will come back to her if their love is meant to be.

Jonathan finds this situation perplexing and bizarre, but he is able to argue back that she should write her number down on something to balance the equation.  Sarah decides to write her name and number in a book entitled Love in the Time of Cholera by Gabriel Carcia Marquez. She will later sell it to a used book store somewhere in NYC. If it so happens to fall in Jonathan's hands, then will she allow their love to blossom.  

Several years pass and they are about to get married to other persons.  But then Fate steps in, and our adventure begins.
