I'm a rational man dogged by small superstitions.
If I spill the salt I make sure to quickly throw a pinch over my left shoulder. I pick up pennies, there's the rhyme: "See a penny, pick it up, and then all day you'll have good luck" and I know it at least dates from the day when you could buy a beer with a penny, now there's nothing you can buy for a penny, still I pick them up.
I stare at funerals. If I'm off garage saling or to thrift shops I consider it a good omen if the bus is there, or shortly there, the time the bus takes to arrive is directly proportional to the success I'll have at the thrift shop/garage sale/ what have you. Reason only consoles me when the bus is late.
And there's a spell I have, the only one really, to bring the bus I light a cigarette.
