Are you superstitious? I don't think I am particularly. I mean I don't worry about Friday the 13th, I don't worry about the number 13 at all, be it a date, a floor or a room. I don't walk under ladders because that's just common sense, I don't worry about black cats crossing my path, in fact we had a black cat for years. I don't worry about breaking a mirror and having 7 years of bad luck unless I cut myself and haven't updated my tetanus shot lately. I don't open umbrellas in the house, not because it's unlucky, it's just that I worry it won't close and I won't be able to get it out the door.
On the other hand, if I spill salt I will always throw some over my shoulder, I believe that bad luck or things come in threes and if my left hand itches I'm hopeful that some money is going to come my way.
