A woman once told me about something that happened to her when she was 10 years old.
It was school holidays and her family had booked a flight to go from her home town of Amsterdam to New York. She was so excited about going. Unfortunately, two days before departure her mother developed a severe ear infection, meaning she couldn't fly. As a result, they cancelled their trip. Magda was very angry at her parents for this.
On the day they were supposed to fly, the plane that they were supposed to be on crashed leaving no survivors. You'd think that the woman would have been grateful, after all, her mother's ear infection had saved her life, but to this day she is angry at her mother for having ruined her holiday.
