Behind the movies scenes, behind the protagonist's smiles,  
Beneath the orchestra's strings, back of the ticket booths,  
There is a message found in all of this;  
That this is the now, and you are here alive,  
As alive as anything that ever lived,  
Furthermore, this is not a dream;  
Though if it were, it would be the most wonderful dream imaginable,  
Even though it's impossibly, unbelievably true,  
And you want to keep on having it- 
This dream- for as long as you can,  
Because being alive is such a splendid 
Once-in-a-lifetime, first-run, no-repeat event;  
It's worth everything it has ever cost you or anybody else,  
Because you're now one of the wealthiest creatures on the planet- 
In all your improbable aliveness.
