Many years from now, the sun started dying. There was ever less light and warmth for animals and plants on earth, and they were slowly dying. After a while, only two squirrels survived. As chance would have it, they lived in holes on neighboring trees, and they knew each other from their earliest days. Each of them had plenty of nuts stored away, and they ate them day after day while everything around them was turning to dust. “Look,” one of the squirrels said to the other with conviction, “we’re so clever to be the last ones on this planet!” Having nuts aplenty, they enjoyed every day. There were many nuts left when both squirrels reached their old age. One day, they realized that the end was nigh. “Look,” the other squirrel said to the first one with equal conviction, “we’re so clever to have reached our last day with so much of our sustenance yet untouched!” As the sun flickered away, the squirrels died and shriveled away next to each other while the remaining nuts first froze and then turned to dust in the growing chill. The moral: It is never too late to be clever.
