Many television programs are very realistic. One who watches TV often feels that whatever happened in the film could as well happen to him. With only a little imagination, every man in the street becomes a thief, a spy or a murderer.(16)Jane had been watching a spy film at a friend’s house. In it, a young girl had been followed and murdered. On her way home, Jane felt a little frightened walking to the station.(17)She took the train back to the center of the city. A man sitting opposite her, reading a newspaper, glanced at her. Remembering the film and feeling very uncomfortable,(17)she got out of the train and went to the bus stop. When she got on the bus, she found the man was following her. As long as she had been with other people she wasn’t frightened, but when she got off the bus, the streets were almost empty. She walked as quickly as she could. She could hear footsteps following her but she didn’t dare to look. After what seemed to have been hours, but in fact only a few minutes, she reached the front door. She felt for her keys, but was unable to find them because she was so frightened. The footsteps stopped behind her. She felt a hand on her shoulder. Instead of feeling hands round her neck, however, she heard a pleasant voice.(18)"I apologize if I frightened you. I’m your new neighbor. I thought I recognized you in the train, but I wasn’t sure. "
