Silence is diamond

A boy saw a tree that had a hole. In the hole he saw a small snail and lots of diamonds. He felt excited and went to school. He told all his friends, when they were returning home, they stopped to see. But the diamonds were gone. They laughed and said its a snail on bulshit. He felt sad and went back home. He didn’t tell anything to his parents, put him to sleep. That night he saw the snail telling him in his dream that “Don’t tell anyone”. Next morning he remembered the part of his dream. He went to school, checking for the diamonds and they were there! Again!. So he decided to take one with him. He went to school and told nobody. On the way back he saw the diamond were there. After reaching home, he told his parents the story and they were surprised. His dad ran to check, while he was trying to find the piece he took, from his bag in the room. His mother was getting the table ready for dinner. He found the piece and on the way to show his mom, he was asked for a jug and he went to get it filled with water and diamond went down the drain. Father returned , found bullshit. Same night- no dream. Next morning, snail says again. Boy doesn’t tell. Diamonds stay. Takes one, doesn’t tell, diamond ‘stays’
