Our new home is in a little cul-de-sac, and there are always kids riding their bikes about or throwing a ball, so we wanted to make sure that people knew we were taking part in our tiny community.
We ended up with about 30 kids in total, in groups from 2 to 6 in size, some with parents watching from the end of the drive, some clearly trusted to look out for each other. Mostly they told a joke (and I discovered that 7 year olds don't understand that "That was *terrible*" is a compliment when it comes to jokes), one group did a song all together, and two played instruments (one had a violin, accompanied by her mother on a tiny drum. The other had a melodica).
The older kids made sure that the younger kids all got a go, and they were terribly polite, nervous, and excited. I was delighted with the whole evening, and we're looking forward to next year already. And, in a couple of years, taking Sophia round the neighborhood ourselves.
Sophia loved the pumpkin:
Even more when it was carved and had a candle in it:
This is how you summon the neighbourhood children:
