the following sentences r from a famous film<The Big Blue>,please appreciate it!
a boy said to his girl:"Do you know what you’re supposed to do to meet a mermaid? You go down to the bottom of the sea,where the water isn’t even blue anymore,where the sky is only a memory,and you float there in the silence.And you stay there,and you decide that you’ll die for them. Only then do they start coming out. They come and they greet you and they judge the love you have for them. If it’s sincere,if it’s pure, they’ll be with you and take you away forever."
