CULTURAL NOTE The most common things that people in the UK and US consider to be unlucky are Friday the 13th, walking under a ladder, and breaking a mirror. Every time a Friday is the thirteenth day of the month, people expect more accidents and problems to happen. Many people also avoid walking under a ladder that is leaning against a wall because they say it will bring them bad luck. People also say that you will have seven years of bad luck if you break a mirror. People in the US believe that it is unlucky if a black cat walks in front of you, but in the UK this is considered to be lucky. Although people say these things are unlucky, few people really believe that they are. → see also Cultural Notes at LUCKY, SUPERSTITION
