A boy who did not know what an echo was cried across a valley, "Who is there?" The echo answered, "Who is there?" The child could not see who spoke those words and he asked, "Who are you?" Back came the words, "Who are you?" The boy thought someone was trying to tease him. So he shouted, "Please stop it!" The echo repeated, "Please stop it!" Just as the child was becoming bewildered by the echo, his mother explained to him that no one was trying to tease him, that it was only an echo of his own voice that came back to him. The child thought about this for a moment, then cried out, "I love you!" Back came the words, "I love you!" The child enthusiastically shouted, "You are so good!" The compliment was returned to him and the child became happier and more enthusiastic about life. The moral of the story is that what we give to this world comes back to us.
