I'm sure all cultures have their own superstitions, but being from the South, I happen to think ours are the most fun - and even being here in WV for 25 years, I still abide by many of the Southern superstitions.
This morning, my left palm was itching like a mofo. I scratched it like a madman. In the South, we're told that if your left palm itches it means you'll be getting a bill or owe money... that money will be leaving you. No one wants that, so the cure for that is to scratch it. Conversely, if you right palm itches that means you've got money coming your way or you'll come into money (and I don't mean wearing a gold diaphragm ... get back to me when you get that one).
Anyway, you're not supposed to scratch your right palm. You don't want to discourage money from showing up, do you? It's hard to remember that one.
Also, if a black cat crosses your path, that's bad luck. But, you can put a hex on that bad luck by cussing.
I love cats, but if I see a black one, you can bet in my head, I'm thinking "G*d D**n, M****er F***er, Shit, Shit, Shit." I think the longer the string of cuss words, the more effective it is.
Of course, don't walk under a ladder! And, a broken mirror is 7 years of bad luck. Some of these things have NO CURE - so try to avoid these situations!
Some of them are silly, but I still do them - like when I twist the stem off an apple, for every twist, I say a the alphabet. Whatever letter the stem falls off on, is supposedly the first letter of the last name of the person you'll marry.
If you know my last name, you'll know I never got that far with an apple stem.
I heard so many growing up, I can't remember them all. Just the biggies: ladders, black cats, mirrors.
And if you know how stingy I am with a penny, of course I remember the money ones!
The Evil Twin likes to joke that I can pinch a penny so tight, I can turn it into copper wire. He's just jealous of my mad money saving skillz. :-)
