I think the only reason to post would be to try to get that craft item back if she did not know who the kids were. Post something like does anyone know who the we kids are so we can get our craft item back or something along those items. If she the kids I'd just go to the house and ask for the craft back. To be honest who cares about the candy.
I agree if you leave a bowl out for kids to take what they want ..you have to assume some kids are going to take the whole bowl.
We did that one Halloween as we were going out to dinner after our kids finished their trick or treat. So if you have a neighborhood of kids you will find out who took that candy without a camera. So yeah this happened to us we came home the bucket was empty ... Which we were hoping for and one of our neighbors told us so and so came and just empty the bucket in his bag.
So what ... And not surprised it was the brat if the neighborhood. That is about as far as it got.
I wouldn't agree if this woman was trying to shame them but I would not ream her over the calls for publishing it either.
