I don't consider myself superstitious at all, but one thing I never do is turn my back to the ocean.

We've got a lot of local superstitions here: don't whistle at night (you'll attract ghosts); don't cut your nails at night (it's bad luck); putting jars of water on your lawn/yard will prevent dogs/cats pooping on your property; a huge black moth in or outside of your house means a deceased loved one has come to visit; never point in a cemetery (it's bad luck); if a young kid bends down and looks between his legs that means mom and dad will be expecting a new one soon...the list is endless.

My most favorite one, though, is the one about chopsticks in your rice. Never, ever stick your chopsticks upright in your rice bowl. It's bad luck, or as the Japanese call it, bachi.
