Yesterday evening I was watching a new film on TV. While I was watching it, my little sister was doing her homework in the next room. Suddenly, she ran into my room because she needed help with maths. When she opened the door, the hero of the film was fighting with a big monster. The noise from the TV scared her, and she quickly went back to her desk. After I finished watching the film, I helped her solve the problem.
