Halloween seems to be a thing now; at least in Sydney's eastern suburbs where I live. Ghoulish house decorations are increasingly the go and parents/guardians are taking to the streets before sunset with their little darlings in tow each holding a bucket for all those treats they hope to collect. I gather that is the aim.
I don't know why parents would feel that extorting loads of lollies from neighbours and strangers is a desirable activity for their children but there you go. Commercialism and marketing trump sense.
Here is one of my neighbourhood residences dressed to kill for the evening.
