Hi, I am Ray. My Dad is not a famous person or a national hero. But he is my hero! He is always fun. I can play-fight him and he doesn't mind. He isn't a person who won a championship or walked on the Moon or saved people in trouble but he is kind and clever and he is never bored to be with. My best days are the days that I spend with my father. He knows a lot about space exploration and the achievements of scientists. I like his stories about space expeditions and astronauts.Sometimes my friends join us to listen to his stories and I am proud of my Dad.
