Are you superstitious??
I heard a lot of superstitions growing up:
Knock on wood to avoid bad luck.
Do not walk under a ladder.
Friday the 13th
7 years bad luck if you break a mirror
If you spill some salt, take some and throw it over your left shoulder.
Find a penny and pick it up. All the day you'll have good luck.
Step on a crack, break your mama's back.
Don't cross a black cats path.
What have you heard, or what do you believe?
I always do the "knock on wood", penny pick up and tossing salt over my shoulder.
