What superstition did you believe as a kid?

Since it's Friday the 13th, I thought I would ask this question.
Breaking a mirror equals 7 years of bad luck
Walking under a ladder
Black cat crossing your path
Opening an umbrella indoors
Stepping on a crack, break your mother's back
Another superstition
None
