I was walking home last night and a black cat ran across the path I was walking. This is considered in my culture at least to be a sign of bad luck. Does it mean that in your countries also?
I don't believe in luck per se, but it is interesting the things which some people think bring them luck, be it good or bad. I know a woman for example who thinks opening a packet of crisps (chips) upside down is lucky...
Some more common examples are things like walking under a ladder is bad luck or breaking a mirror is seven years bad luck. Things which bring good luck include carrying the foot of a dead rabbit? say what? Lol
Can you think of any more? What things are lucky in your country?
