Trick or treat

Maybe because I'm a different generation as there was no such thing as trick or treat when I was young but the idea of what this mother describes is to me repugnant. Apart from the morality issue especially as we know it is exploited by older children to inflict terror on those who don't bribe them to go away. Then there is the children stuffing themselves with sweets - what a way to raise children. No wonder children's teeth suffer.
