The two cubes of sugar.
There were two cubes of sugar wondering what to do with their sweetness. One cube thought, “I am so delicious, I want to share my sweetness as widely as I can.” This cube, spying a tub of water from which the animals drank, leapt into it, where it promptly dissolved. And indeed, animals drank the water and each thought “hmm, this water is a little better today.”
The other cube then thought: “I could do the same as my sibling, but I will not. Once dissolved I would no longer be the well formed cube I am. Better that I end up the prize of a single tongue, that I might be known and loved as my true sweet self, than to end up watered down for the vague enjoyment of many.”
