You excitedly prepare for a football game with friends, only to find the TV showing fuzzy images—a classic example of Murphy's Law: if anything can go wrong, it will.  This highlights our tendency to remember negative experiences, like choosing the slowest supermarket checkout line or encountering all red lights when late.  Robert Matthews explains this isn't bad luck but a probability issue; for instance, the odds of selecting the fastest cashier are low.  He famously debunked the buttered toast myth, showing equal chances of it landing buttered-side up or down in an experiment.  However,  blaming Murphy's Law for everything is wrong;  problems like a broken water heater or missed bus are due to other factors, not mere coincidence.  Ultimately, responsibility for events, like losing computer files without a backup, rests with us.
