[Oiseau the Little Bird!]

I was listening to a podcast of the Pagan variety, and the subject of superstition came up, and I got thinking about it and religion.
Now, I don't mean to be ignorant, but I try to learn about everything as much as I can, and the only way to stop being ignorant is to ask questions. So I ask everyone -- of every faith system, but particularly Christians (just because I'm curious) -- how do you deal with superstition? In your particular practice, would superstition be considered anti-religious (i.e., are some traditional superstitions considered so be sinful)? What superstitions do you hold close to you? You know just stuff like that. Thanks a bunch!
