Or rather the perceived doom that they may convey?
I am not superstitious about anything else. Broken mirrors can fuck off and black cats can do one.
But one single magpie puts the right willies up me as harbinger of ill will.
Someone once told me that if you spit at them it counteracts the potential 'sorrow'
Spitting is the most revolting habit available, so instead I just do a little bubble to myself. Only last week I did a full-on dribble down my chin and got a horrified look from a passer-by.
Please tell me what a twat I am and why one magpie spotted on a school run will not lead to my imminent ruin.
