Theory:

The poem is about a kite. Almost everyone loves kite-flying, especially when there is a breeze. The poet describes how the kite looks beautiful in the blue sky when there are no clouds. The poet compares the kite to a ship. As the ship sways with the wind, the kite, too, depends on it to fly higher. When the wind drops, the string gets loose, and the kite is pulled back. And again, when the wind blows, the kite soars higher and higher. The kite makes the sky look more beautiful. Eventually, the string will be cut off. As a result, the kite will drop itself on a tree and would get torn.
