What is the summary on the ass and the load of salt?

"The Ass and the Load of Salt" is a fable about a donkey that carries a heavy load of salt for its master. One day, as they cross a stream, the donkey realizes that the salt dissolves in water, making its load lighter. Delighted, the donkey begins to deliberately immerse its load in water, leading to increasingly lighter burdens. However, when the master catches on, he switches the load to a sack of sponges, resulting in a heavier burden for the donkey, teaching it a lesson about the consequences of trying to cheat or take advantage of a situation.
