In the story a very old man with enormous wings,what important insight did the story convey to you about life?

I don't have the Prentice Hall version of the text, but I've always felt the most important insight in this story to be the acceptance of what we're blessed with....... that when we're given a gift, we are to accept the gift with gratitude expecting nothing more. The angel was a gift, he came to gift both the child and its parents with a life that would have been lost, but the parents wanted more. Thus the giver wasn't accepted for the angel he was; he was made into a freak show...... the gift thrown back in his face.
