Don't blame the night, blame the parents - we used to have Halloween parties when the kids were younger and we'd take them trick or treating, but only to neighbours, generally okayed in advance. But we're not bothered by casual callers, my understanding of the unwritten code is that if a house displays Halloween decoration then it's ok to knock, so we have lanterns etc and keep a big tub of sweets by the door. Generally 8pm is the limit but we accept callers up to 9pm, I have given the bums rush to the odd teenager(they're all odd in some way

) and we never give out money.
It's not as much fun as it used to be, the kids are older now so the 'inhouse' excitement level isn't there anymore and we don't dress up now either - yes I was always Frankenstein or a Zombie and yes little makeup required

But my sons do the door answering now and you can see that they actually get a bit of a buzz out of giving sweets to the little kids and admiring, and feigning fear at, the costumes.
But each to their own, if this thread was about carol singing then my view would be markedly different.
