What's Wrong with this Picture?

 
They'd always been the best of friends;  
As tight as smoke and fire.  
But, secretly, she wondered why  
They'd never taken it higher.  
 
He had a slew of girlfriends.  
She'd known a few men of her own  
But intimacy, of any kind,  
Between them, was never shown.  
 
One day, she decided to ask him  
How the circumstance came to be  
"When it comes to passion," she asked.  
"Why don't you think of me?"  
 
"No chance that can happen." He said,  
Without hesitation, or doubt.  
"I'd never consider getting that close  
To someone I care about."
