even though I've just been badmouthing Denmark in another thread, in Denmark it is pretty unlikely to be gone - like less than 1% chance I would say, especially if you just do it for Halloween night which is the only one that it would be important.
"I don't know where you live, but where I live..." is typically a phrase meant to imply that the properties of "where you live" are vanishingly rare, but that's not the case with high-trust neighborhoods. In the minority, yes. Not bizarre or unheard of or restricted to the wealthy, though.
Lot of haters in this chat but I think this is delightful and I'll definitely try it! We typically sit out on our steps and greet Trick or Treaters in person; I think a talking pumpkin will be a real hit with the kids, and I am quite sure no one will steal it while we are sitting right there!
