With this being Friday the 13th, I thought I'd look around the web for superstitions of one sort of another. But first, some I have crossed paths with over the years:

If you leave a house and come back in for any reason, you have to sit down before you leave again to avoid bad luck.

It's bad luck to rock a rocking chair with nobody in it.

It's bad luck to eat in the bathroom.

To have good luck for the new year, on January 1st, you have to have a meal with pork, black eyed peas, cabbage and cherries.

Now, here are some good luck superstitions I found on the web:

Good Luck: Fingers Crossed - By making the sign of the Christian faith with our fingers, evil spirits would be prevented from destroying our chances of good fortune.

Good Luck: Knock on Wood - It was believed that good spirits lived in trees, and that by knocking on anything made from wood, we could call upon these spirits for protection against misfortune.

Good Luck: Saying God Bless You When Somebody Sneezes. When the great plague swept Europe., sufferers began sneezing violently which was a sign of death. The Pope therefore passed a law requiring people to bless the sneezer. At the same time, it was expected that anybody sneezing would cover their mouth with a cloth or their hand. This was obviously to stop the spreading of the disease, but many believed that it was to keep the soul intact. Sneezing 'into the air' would allow the soul to escape and death would be imminent. Up until this time, the opposite was true. Those who sneezed were congratulated, as it was believed that a violent sneeze would expel evil from their bodies.

Good Luck: A robin flying into the house

Good Luck: Sneezing 3 times before breakfast

Good Luck: Meeting 3 sheep

Good Luck: Looking at the new moon over your right shoulder

Good Luck: A 4-leaf clover

Good Luck: Spilling wine while proposing a toast

Good Luck: Putting a dress on inside out

Good Luck: 9 peas in a pea pod

Happy Friday the 13th!
