The fox played a prank on the stork by giving her a bowl that she couldn't use because her bill was too long and thin. So the stork invited the fox over for dinner and did the same thing the fox did to her. She gave the fox a narrow jar that only she could fit her bill into to eat the soup, but the fox's snout was too large to fit into it. The universal theme would probably be: treat others how you would want to be treated.

This fable illustrates the importance of empathy and consideration for others. By treating others with respect and kindness, we can avoid hurting them and potentially facing similar consequences ourselves. It emphasizes the Golden Rule: do unto others as you would have them do unto you. In other words, the way we treat others is often a reflection of how we want to be treated in return.
