In the garden of Johnny’s home was a tree in whose branches birds had built a nest. He was thrilled when one day, climbing up, he found four eggs in it. Almost daily now, he visited the nest. Then the family went away for the school holidays. The first thing Johnny did on their return was to climb the tree to look at his nest. He was most upset to find that all that was left of the eggs were empty, broken shells. Sobbing, he ran to his father telling him how the eggs were ruined. “No, my son” his father told him “you are mistaken. The best parts were inside, and they have become beautiful birds which have flown away.”
