What is Roman?  My son looks up to and asked me. It will be long and too much talk about it. I need too much word to explain that. Everyone once had it inside. Someone has it also today. They look at distance and invites you. Invites you to a journey. 
What is the River?  You ask me pointing the boat there. It leads to the valley , there the king lives. Many men from far countries are on the boats. Let's go closer. Let's go to hear the story of the world. 
What is the reason why everybody is in a festive mood?  Also baby and dogs are singing together. Open the Port! We will look at the world sea. Open the port, yeah! Let's go to the world.
