The Buddha was born as a parrot. He had a son. When he grew up, the son cared for his elderly father, bringing him food.
One day the son flew to an island full of mango trees. He brought back a mango.
"Beware, my son," said the parrot’s father. "That is too far; do not go to the mango island."
But the son did not listen. He flew again to the mango island, and then he grew so tired flying home that he fell into the ocean, and a fish ate him.
The Buddha waited, but his son never returned.
