Role Playing

Did you ever feel in living your life that you are just playing a role in a play that has already been written?  I often do.  It seems like no matter what I do, the outcome is always the same, already written down somewhere.  It's like going to an opera that you've already been to millions of times.  You know the ending.  The overweight diva will die of consumption, belting out a strong aria in between coughing spasms and death rattles.  It's very sad but we still go.  Why?  Voyeurs?  Music lovers?
