The beginning i think that It is about William trying to find a cure for unhappiness and make take the unhappiness from his mom. He finds the cure from a homeless man he and his mom met which his mom told him not to look.
The middle he went in his room the he went downstairs. then went out side. by the homeless man. He gave the homeless mad a coin. and the homeless men balled up his fist and stayed there. and the boy went into the house
The end willie wanted to fish in the cave and they think the homeless man is nice and kind
