I throw salt over my shoulder , Knock on wood a lot , Never say thankyou for a plant someone might give me and woun't let them tell me thankyou for a plant i might give them , I would never give knifes as a gift . I always leave a coin in a purse i get rid of . and im sure i do other things just out of habit and i can't think of right now .. I find it good luck when a cat crosses my path and Friday the 13th is lucky walking under a ladder is fun too.. lol
I am never sure which direction the black cat should take for good luck also over here in the U.K. we acknowledge Mr Magpie. When we see them we say 'Good morning Mr Magpie' etc if you see one it is for sorrow, two for gold three for a secret never to be told etc.
