This is a very cute and significant story.
At first, missing piece was too independent, and he always tried to find a roll that can fit him. But it changed when he met Big O. Big O told him that he could roll by himself. He didn’t believe at the moment of hearing it, but he finally did succeed by his effort.
After reading this story, I think every one should not be too independent to others. Everyone have his own talent. Never forget your own advantage and take good use of them.
