What silly superstitions do you find yourself doing/following even though you know they are just silly superstitions?
I have three.
I say "knock on wood" or "wish me luck" even when I know luck has nothing to do with it.
I won't flip a calendar early. I know it won't cause anything bad to happen but I still won't do it.
Sports superstitions. If my team wins, I have to wear the same outfit the next time. I know it has nothing to do with it but I must have my "lucky" earrings on for every game.
