Short movie: Mermaid

The main character in the short movie is the boy who likes imagination. One day, he met a little fish. Then he began daydreaming : a little fish is a mermaid and he made friends with a mermaid. He believed that it is the fact and tell about it to his parents, but they didn't believe it. He wanted to someone admits a mermaid. However, nobody admit a mermaid. It is the conflict for him. At the end, everyone admits his thought about a mermaid and he will live with a mermaid. The theme of the short movie is freedom of speech. A long time ago, we can't say our opinion freely, but recently we allow to say our opinion freely. I think this movie show the process.
