Imagined bit of conversation

"What is WHN up to?

 

"I don't know."

 

"You don't !?!  Why not?"

 

"I just don't."

 

"Well! Don't you think you should?  I thought you were the best of buds."

 

"Who are you to say?  And besides, if you are so curious, why haven't you found out for yourself, instead of happening to ask me on a chance encounter?  Hmmm?!"
