人不是魚，怎會了解魚的憂愁。

魚不是鳥，怎會了解鳥的快樂。

鳥不是人，怎會了解人的荒唐。

人不是鳥，怎會了解鳥的自由。

鳥不是魚，怎會了解魚的深沉。

魚不是人，怎會了解人的幼稚。

你不是我，怎會......了解我。

The person is not a fish, how can (it) understand fish's sadness. 

The fish is not a bird, how can (it) understand bird's joy. 

The bird is not a person, how can (it) understand person's absurdity. 

The person is not a bird, how can (it) understand bird's freedom. 

The bird is not a fish, how can (it) understand fish's deepness. 

The fish is not a person, how can (it) understand person's weakness. 

You are not I, how meeting.....  (you) understand me.
