Egg Timers

Two egg-timers sat across the negotiating table from each other.
One was an antique of iron, clear crystal, and sand.
The other was made from plastic, filled with a fine powdered silica.
Both were cracked and pitted, weary of endless war. But neither was yet willing to yield to the other.
Another arbiter was led into the room, and he sat down at the table.
“I’m sure we can find something in common,” said the arbiter. “You’re an egg-timer, and you’re one too.”
Five hours later, the arbiter left for a cigarette and never came back.
Just like the others.
