Musings of a Bystander

Bystanders ... are on the stage but are not part of the action.  They are not even audience.  
The fortunes of the play and of every actor in it depend on the audience whereas the bystander 
has no effect except on himself. ... Bystanders reflect -- and reflection is a prism rather than 
a mirror; it refracts.  Above all, he sees differently from the way actors or audience see.
