We hung out our lit pupkin head in the porch because we were having a Hallow-een party, and we got loads ot TOT'ers calling, all got sweets.
A few were obviously teenagers, but all the little ones either had an adult with them on the doorstep, or at the drive entrance a few feet away keeping an eye on them.
One chap - a Scot - said it was tradition for visitors to come in and tell a joke, so he and his daughter, about eight or so, came in and she told a couple of jokes and took some sweets, what a lovely idea if it's the custom there.
When our tribe went out to do their TOT'ing, several adults went along, not only to watch them, but to enjoy the fun - everyone around us is in the spirit, and they cam back with tons of sweets!
