REFLECT: ITS ALL SO RELATIVE

There is a story of the emperor, the sage, and the crab.

One day, the emperor was walking on the beach with the sage, and saw a crab, walking
sideways. The emperor asked the sage, "Why does the crab walk sideways?"

The sage said, "I'll ask the crab." He picked up the crab, asked it, "Why do you walk sideways?", put it next to his ear, smiled, nodded, and  placed the crab down.

"Well, what did the crab say?" asked the emperor.

"The crab asked me why we walk forwards." replied the sage.
