I've just collapsed my umbrella after drying it off and made very sure I didn't hold it over my head. I acknowledge magpies but I don't say anything out loud. I don't walk over 3 drains or under ladders. I'm a dog person but quite fond of black cats (and other cats too).
What are you superstitious of? And if anyone has the roots of any superstitions I'd be really interested to hear them!
