I never trick-or-treated as a kid, nobody did because it hadn't been imported from the US yet (I think the first proper look we got over here was that scene in ET).
We did penny for the Guy, where we'd make a Guy for the November 5th bonfire*, and drag it door-to-door asking for small change off anybody impressed with our handiwork.
These days, we get quite a few kids trick-or-treaters. The first ones are the tiny kids, who have no real clue what is going on. They tend to arrive just as it goes dark, and as the night goes on the kids get older and the costumes better.
The end of the night is my favourite - that's when the barely-still-teens turn up. Very few boys, but quite a few girls (any boys seem to be with girlfriends), and the general theme seems to be slutty zombie/vampire school-girl; short, disarrayed school uniforms, zombie make-up, ripped fish-nets...
If I was their dad, I'd not let them out of the house like that, but when they turn up at my door and beg for treats, I'm not going to complain.
Actually, maybe the early evening is also my favourite - it's little kids at my door, but they're brought round by yummy mummies, using their kids as an excuse to dress up as sexy witches.
Ah, heck, I love the whole evening.
