It's Friday the 13th, so here's a rundown of some famous superstitions . . . and where they started.
1. Plucking the petals off a flower to play "she loves me, she loves me not." It comes from a game in medieval France, called "to thin the leaves of a daisy." The English saying came around after it was printed in a 15th century songbook.
2. Throwing a coin into a well to make a wish. Since wells are a source of water, they symbolized fruitfulness. So if a woman stood by a well and made a wish, it was supposed to come true. And back then she usually wished for a husband and children.
3. Kissing under the mistletoe. It's thought to have originated at ancient Greek festivals, as a way to ward off evil and welcome love into people's homes.
4. Throwing rice at the bride and groom. It comes from ancient Hebrew and Egyptian cultures, and is a symbol of fertility and good fortune.
5. Carrying something old, new, borrowed and blue at your wedding. These are based on a couple traditions. The "old" shows a couple's intention to keep their existing family connections, even as they begin a "new" family.
"Something borrowed" is an item given to the bride to symbolize the love and support of her friends. And the "blue" symbolizes purity, fidelity and loyalty, going back to Biblical traditions. (Match.com)
