The sea is endlessly but you think you could do it anyway. So when you go to the beach, you put your swinsuit on and you go ahead to the sea. You start swimming. After a while you get afraid because you don't touch the sand and you can't see if there are fish under you. You think you've just gone too far from what you've always known. You become coward because of what? There are no reasons but you don't swim anymore. You consoles yourself saying that you need some goggles to see the fish and all the creatures who live in the ocean. You come back to the seashore and you sunbathe.
And that's how life feels like.
