I find it an interesting opportunity to observe the different facets of human nature. I live in an area with lots of young families and I like seeing the hand crafted decorations that the family have made as a craft exercise. Who are the people who make their own, and who obviously spends way too much money on that stuff? Which children take only a small portion of treats, making sure there's plenty left for other children, and who grabs repeated handfuls of treats or even pours the entire treat bowl into their goody bag! Which parents dress up and get out there mingling with others in the pleasant early evening, laughing and handing out treats? Which parents put a bowl out and play possum? Which parents deliberately ignore the blatant greed of their children and fiddle with their phone, or actively encourage their children to take all the treats! It is endlessly fascinating for me to observe and I am totally there for it.
