Michael was selling a fine horse

Michael was selling a fine horse, and his friend Liam came over with the intention of buying it.

“How much is it?” asked Liam, and Pat told him “500 dollars.” Liam was startled, and said,

“But sure, I could give only 25 dollars for even such a fine horse.”

“Done!” said Michael. Liam was surprised again. “How is it you came down so fast?” Michael smiled and said,

“25 dollars is what he’s worth, all right, but you’re my friend, and I thought you’d like owning a 500 dollar horse.
