His friend said, "What? You must be crazy. You couldn't possibly hear a cricket in all of this noise!"

"No, I'm sure of it," the Native American said, "I heard a cricket."

"That's crazy," said the friend.

The Native American listened carefully for a moment, and then walked across the street to a big cement planter where some shrubs were growing. He looked into the bushes, beneath the branches, and sure enough, he located a small cricket. His friend was utterly amazed.

"That's incredible," said his friend. "You must have super-human ears!"

"No," said the Native American. "My ears are no different from yours. It all depends on what you're listening for."

"But that can't be!" said the friend. "I could never hear a cricket in this noise."

"Yes, it's true," came the reply. "It depends on what is really important to you. Here, let me show you."

He reached into his pocket, pulled out a few coins, and discreetly dropped them on the sidewalk. And then, with the noise of the crowded street still blaring in their ears, they noticed every head within twenty feet turn and look to see if the money that tinkled on the pavement was theirs.
