What's so funny? (Reading)

You have been studying for an important examination. Passing will help you get your dream job. You haven't slept well in recent weeks and are often irritable. Your friend hasn't seen you in a long time, so he/she stops by your place to cheer you up.

You are on a crowded elevator when it suddenly stops between floors and won't move. Someone calls for help, but in the meantime you are all waiting. The passenger standing next to you makes eye contact briefly. He mentions a movie where the same thing happens.

You are in the hospital recovering from a serious car accident. You have had several surgeries and will be missing at least one month of work. You are in a lot of pain and are unable to do things without the help of a nurse or your family. A relative comes to visit you and tells you a funny story about the last time she was in the hospital.

Your home and neighborhood have been completely destroyed in a flood. You have lost most of your belongings, but your family is safe. You are temporarily staying in a government shelter. A former neighbor sees you in the shelter and comes over to talk. He jokes that he has been meaning to renovate his house for years and it looks like now he'll have a real reason to.
