I met a seer.  
He held in his hands  
The book of wisdom.  
"Sir," I addressed him,  
"Let me read."  
"Child -- " he began.  
"Sir," I said,  
"Think not that I am a child,  
For already I know much  
Of that which you hold.  
Aye, much."  
 
He smiled.  
Then he opened the book  
And held it before me. --  
Strange that I should have grown so suddenly blind.
Stephen Crane
