Script:
Woman: If we make the 8:10, we′ll be home by nine o′clock.
Man: We don′t have a chance. It′s late already, and we′ll never get a taxi.
Woman: Then let′s walk. It′s not far to the train station. I′m sure we can make it there in 15 minutes if we walk fast.
Man: That′s a great idea. Let′s try it. We might make it in time for that train, and, anyhow, my doctor recommended that I get more exercise.
