Jacinda Barrett Instagram – My 4 year old son wrote a book. Here it is: The Solar System When the solar system vibrated Mars goes around the sun. The sun goes around Mars and then Mars tries to catch earth and then Earth grabs Mars and takes it to the sun to get really hot and warm. Then Mercury which is really cold goes close to Mars, too. Mercury wanted to be friends with Mars, but Mercury freezed on ice. The End. #instapoet #solarsystem #mars #mercury #sun #earth #friend
