Art probed the bag's orifice a while longer, then happened upon the release. The bag sighed apart, falling in three petals, and revealed its payload: a small, leather-worked box with a simple brass catch. Art flipped the catch and eased the box open. Inside, in a fitted foam cavity, was a gray lump of stone.

"It's an axe-head," Fede said. "It's 200,000 years old."

Art lifted it out of the box carefully and turned it about, admiring the clean tool marks from its shaping. It had heft and brutal simplicity, and a thin spot where a handle must have been lashed once upon a time. Art ran his fingertips over the smooth tool marks, over the tapered business end, where the stone had been painstakingly flaked into an edge. It was perfect.

Now that he was holding it, it was so obviously an axe, so clearly an axe. It needed no instruction. It explained itself. I am an axe. Hit things with me. Art couldn't think of a single means by which it could be improved.

"Fede," he said, "Fede, this is incredible —"

"I figured we needed to bury the hatchet, huh?"

"God, that's awful. Here's a tip: When you give a gift like this, just leave humor out of it, OK? You don't have the knack." Art slapped him on the shoulder to show him he was kidding, and reverently returned the axe to its cavity. "That is really one hell of a gift, Fede. Thank you."

Fede stuck his hand out. Art shook it, and some of the week's tension melted away.

"Now, you're going to buy me lunch," Fede said.

"Deal."
