I'd say we've had 5-6 groups, about 12 kids total. Most just did the standard 'Trick-or-Treat', but a few of them also told us a joke (which is the traditional thing in Scotland-- they're supposed to do their 'party piece'.)
Knock, Knock.
Who's there?
Boo.
Boo who?
Don't be scared, it's only a costume! :p
This is the most we've had in 5 years, but I put that down entirely to geography. There were only three boys in our old village, but they did come 'round every year.
I wasn't sure what to expect. Some co-workers who live not-too-far-away say they've never had any at all, but I figured since we're just up the street from a primary school, and there are plenty of kids in the neighbourhood, we might get a few. I actually suspect we had fewer than we might have, because of the rain.
