My Grandmother was ScotchIrish and my Granny on the other side was Cherokee, so I guess I grew up with my share of "superstitions." My bf makes fun of me now because I always refer to folk sayings and swear they are true.
Red sky at morning, sailor take warning; red sky at night, sailor's delight.
If you say thank you for a plant it will die.
Plants do better if you steal them.
Itchy palms means you are going to get money.
Itching nose means someone will visit.
Sweeping under a single girl's feet means she will never marry.
If you hear an owl hoot 3 nights in a row, someone is going to die.
Deaths always come in 3's.
It's good luck if a bird or a butterfly lands on you.
Dream something three times in a row and it will come true.
If you dig a hole during a full moon, there won't be enough dirt to fill it back up.
Love those and the idioms that my Grandmother used to say. My favorite was when she would see something tacky. She'd say, "I wouldn't have that on a Christmas tree!"
