She was still obliged to leave the house every day, on her usual hunt for food; and especially on days of bad weather she had no other solution but to leave Useppe alone, his own guard, locking him in the room. It was then that Useppe learned to pass time thinking. He would press both fists to his brow and begin to think. What he thought about is not given to us to know; and probably his thoughts were imponderable futilities. But it's a fact that, while he was thinking in this way, the ordinary time of other people was reduced for him almost to zero. In Asia there exists a little creature known as the lesser panda, which looks like something between a squirrel and a teddy bear and lives on the trees in inaccessible mountain forests; and every now and then it comes down to the ground, looking for buds to eat. Of one of these panda it was told that he spent millennia thinking on his own tree, from which he climbed down to the ground every three hundred years. But in reality, the calculation of such periods was relative: in fact, while three hundred years had gone by on earth, on that panda's tree barely ten minutes had passed.
