In most hotels all over the world, you will not find a room with the number thirteen, and if the hotel is a skyscraper, it will go from floor twelve to floor fourteen. The superstition that thirteen is unlucky can be traced back to a Scandinavian myth. There were originally only twelve gods and then along came the god Loki to make thirteen. Loki was a mischievous god who brought suffering to people. Nowadays, people avoid planning important events on Friday 13th (or Tuesday 13th in some cultures), and if things go wrong on that day, like the loss of a wallet or a key, they blame it on the date.
