Our modern world has done away with the kind of ritual our ancestors thought they couldn't do without. No longer do we need Morris dancers to change the seasons for us, nor do we have to sacrifice any pigeons to atone for our sins, although that would be cheaper than paying speed camera fines and would certainly keep the pigeon population in check.
But rituals are good for humans. They give us the illusion of keeping chaos at bay, so we can shelve our existential terror and get out of bed. Fortunately, we have managed to fill our modern lives with useful new rituals. Here are some rites of passage you celebrate every day.
The Sign of the Trolley
There's no way of telling what the last person did to your supermarket trolley. He or she could have handled a leaky bag of reduced-to-clear raw chicken; a small child covered in sticky things could have sat in the little seat or, worse, stood in it. The Sign of the Trolley, that little wavering hesitation your hand does before you grasp the handle, protects against bacteria but is less effective on wobbly wheels.
