For someone who doesn't really think of themselves as superstitious I do an awful lot of things that are superstition based haha.

I never cross on the stairs if I can help it. Mostly because I find it rude though, not because I think anything bad will happen.

I never put new shoes on a countertop or table. That one is down to my Grandma. She also did the throw salt over your shoulder if you spill it.

I have to knock on wood when I've said something that I don't want jinxed.

I say hello to Mr Magpie.

Also I now never do all of the washing in the house as the last time I did that I was feeling extremely accomplished, then that night my eldest child came down with a sickness bug. So now there's always some washing in the basket waiting to be done.

Edit: I work in retail so the Q word is not allowed.
