A man once said to his son:"Touch the sky and you'll be the happiest man in the world."
So, the son was ambitious to reach his goal of being a pilot someday, somehow. But it seems that when he had actually been on the skies that he had wanted since birth, he was not filled with joy, but remembered the words that his father had said, and what he did to help him acheive his success. But he feels so empty inside, that he wasn't able to share the joy to the one that he had respected so much. His father was old and had all the sickness that an old man would have, but the son wasn't there to take care of him. It all seemed so wrong, that actually the son had listened to the dad's advice and made him proud, but his heart was all but filled with anguish and sorrow...Humans are also the same-We wouldn't know how to appreciate the things around us until they're gone, but who would be so perfect at times?
