"Your thoughts; are they worth a penny too?"
"Can you not guess them?"
"That is not an answer to my question."
"I have not your gift of prescience. I cannot tell if they are worth a penny to you. To me they are worth more pennies than I am ever likely to possess."
"You place a high value on your own thoughts."
"Shall I tell you what they are?"
"If you like. Though, is it worth the trouble, if you are sure that I can guess?"
"Give me leave to tell you them."
"I give you leave."
"I was thinking what fallible creatures we men are."
