Globalisation and American imperialism — many dislike Halloween as an imported American custom, but kids need to know sooner rather than later whose culture dominates the world.
Consumerism — where once the poppets made do with a sheet that had holes cut in it for eyes for dressing up, now there are any number of ways money can be spent on costumes and decorations, teaching the essential lesson that something is only fun if it costs a lot.
Neighbours — for many children in our insular communities this will be the first they learn of the fact that the houses around them contain actual human beings.
Disappointment — there will never be enough lollies in your bag to make you happy.
Snowflakism — Halloween is organised so as not to be scary. In reality, it's good for kids to learn how to handle frights.
As you might have intuited I'm not thoroughly into the philosophy and trappings of Halloween, but that didn't prevent me stocking up. You'd have to be17 kinds of putz to refuse confectionery or even, as some do, take the opportunity to deliver a lecture on the principles of modern economics and society.
So I filled up a bowl with Snickers and Mars bars and Moros and Picnics and waited.
And waited. It was like one of those tragic stories about kids who give birthday parties to which no one shows up.
And I know others who had the same experience.
It seems Halloween is being used to teach another lesson: People are dangerous. They'll poison your candy quick as look at you. Or worse
Parents are increasingly taking children on a circuit of pre-arranged destinations where the inhabitants are friends or family. Children no longer have to encounter people they don't know. They don't have to have it spelt out for them to realise that this is because people they don't know are dangerous.
Well, some might be. But we know kids suffer most harm of all varieties from people they know — even when it comes to being given poisoned candy. The only known case of this widespread fear actually occurring is that of Ronald O'Bryan, who used cyanide-laced sweeties to cover up the murder of his child Timothy on Halloween in 1974.
Scary stuff.
