A man came up to me at the front desk of the library. He had three teeth. I counted them as he spoke to me. There really were just three teeth in there, sticking right up from his mostly empty gums. But I didn't merely count his teeth. I listened to him as well.
He said "How much does it cost for your fax?"
Our copy machine works as an outgoing fax and does a brisk business in that capacity.
"It doesn't cost anything to fax." I replied.
He held up a couple wrinkled dollar bills. "I feel bad not paying anything. I'll just throw in a couple bucks."
"Oh no." I said. "It really costs the library nothing for an outgoing fax. Keep your money."
And I thought:
"Put it towards a dentist."
But of course I didn't say that.
He chewed this over as well as he could, put his two dollars away, and left.
