Teo and the stars (corrected)

Once upon a time there was a boy called Teo. He lived in a bad town where many people were thiefs and buglars. His life was very monotonous because he had to work in a lonely hotel to help his poor family. When the night came he always watched the stars. He dreamed about going to the university to be an astromer, but he doesn't have enough money to do that.
One day he was in a square and suddenly he watched a man with a telescope. He asked him if he was an astromer, and he was one. His name was Tom, and he made a deal with Teo. He said: "Clean my telescope and I'll teach you astronomy". Teo was so happy. He went to Tom's house to watch the stars and learn about them every night. He was so excited with all the leassons.
On a Friday night a beautiful girl appeared in the front of Tom's house. Her name was Polly. They walked a lot about the space, the stars, constellations and planets. Both fell in love that day, so Polly in a crazy idea asked to Teo if he could go to Mars with her. Teo said YEAH! and they kissed in a space rocket, on the way to the red planet
