How utterly ridiculous. I live far enough out of the village that I'm not troubled by them but I'm blowed if I'd bother to make sure my property was safe for the unwelcome little blighters.
I think some primary school parents have an arrangement that if a pumpkin is displayed, the children are welcome to knock the door, and not otherwise. Houses are decorated, the children dress up. I really don't understand encouraging the grabby mentality in little children, but when teenagers go door-to-door it's tantamount to demanding money with menaces. Blasted Americanisms aren't welcome here.
