Small Hall Closed

Emerald walked into the room. She was amazed of how big the room was. There were paintings every where, she guessed they might be paintings of famous wizards. There was a giant chandelier on the ceiling. There were probably almost at least 20 giant tables all around the room. She went over to one of the tables to her right in the corner.
  Emerald didn't see anyone she knew. She took out her book "Hogwarts, A History" and flipped to the first page and started to read. Emerald read about the whomping willow tree, how Hogwarts was made, and the people who helped make Hogwarts.
  Emerald didn't check to see what time it was until she reached chapter 10. When she checked it was already almost 12:00 pm. As she was packing up her book, she noticed that the small hall was almost full. There were a bunch of people leaving, probably for lunch. Then as she was walking out the room she noticed a bunch of kids staring at her. She rushed out of the room.
    It was maybe about 30 minutes before Emerald came back to the small hall. She headed back to the same table she was at before. She grabbed "Hogwarts, A History" out again and started reading. She didn't even care that a lot of kids were staring at her again.
