Please, do not destroy air-castles

The child has built a wonderful castle by sand.
Please, do not tell him about the disappearance of his castle by rain.

The girl has built a wonderful castle of her dream.
Please, do not tell her about the fragility of her dream by life.

The man has built a wonderful castle of his transparent hope.
Please, do not destroy his belief to the future.

Do you know that he will be right if
nobody tells him about the weakness of his hope now?
