My (Irish) mother was very superstitious so I have heard of many of these superstitions before. I never salute magpies but must admit to looking for a second one, for 'joy'. For fun we (DGC) crack the top of a finished boiled egg, but to let the fairies, not witches out. When they were little they swore they saw the fairies flying to the light, usually the window.
I always say 'hello' to the moon when I see it. I don't know why. That just seems to have grown because of my interest in the extra terrestrial!
I will say 'Touch Wood' or 'Cross Fingers' but it is more a turn of phrase than a superstition. I will walk under ladders usually because it is safer than stepping into the street.
Oh and I was 13 on Friday the 13th so maybe that has some significance!!
