Alhaitham was often a recluse who did not particularly like to leave the house. He liked to relax and read books. But one day Kaveh, his roommate, noticed that he was suspiciously long in leaving his room. Then another guy decided to check in. Opening the door, he saw Alhaitham. Alhaitham opened his eyelashes and looked at Kaveh "Didn't they teach you to knock?" Alhaitham asked. He looked pale and ill.
