The strange and wonderful object.

It was a cold dark October night. James and Sarah were walking nervously in the countryside when suddenly they saw a big and wonderful thing that had light. They decided to go and look. They discovered that it was a strange material that they hadn't seen before/were not familiar with. Sarah had a little box with her and put the material into the box.
The next day, James visited Sarah to see the object they had discovered. When he entered Sarah's house, he found her crying. James asked her, "Why are you crying?" Sarah told him that her brother Mateo had stolen the box.
James didn't like Mateo because Mateo wasn't a responsible persoN. He was lazy and always stayed in his house and hung out with his bad friends.
James went to find Mateo. Sarah was very worried. Sarah called her best friend, Caroline. Caroline arrived and she calmed Sarah and made sure Sarah went to bed. Sarah was sleeping when Mateo arrived with his friends. He put his jacket on a chair and went out again. When Sarah awoke, James had already arrived and with the box in his hands.
Sarah thought that James had met Mateo. Sarah was happy and wanted know when James had met Mateo, but Caroline told her that when Mateo went home, she had taken the box.
James and Sarah went downtown to sell the object, but the salesman said that the strange object was a piece of glass.
