I knock on wood
Black cats - well, depends where you are. In Britain they're lucky!!!!!!!
I won't put hats on beds and go nuts if anyone does
I won't put new shoes on a table
(I inherited the previous two - my mum did those!)
If I see one magpie, I have to find another one ("One for sorrow, two for joy....")
I won't sing before breakfast
Things like not walking under ladders is just common sense
Good Lord, I'm certifiable................!!!!!
