Many people are superstitious. They believe in unproven and mysterious facts. Moreover, they are afraid of them. For example, when a black cat crosses their path, they say it’s for bad luck. Or, when they walk under the ladder, it also brings bad luck. It goes without saying that number 13 is an unlucky and evil number. In Britain people avoid having houses or flats of number 13. They don’t even have the 13th floor or room number in hotels. The unluckiest day is considered to be Friday the 13th, although some people simply have fun on this day, turning the superstition into an amusing game.
