Wait for it.
This is good candy karma.
Not sure who the person was who recorded it on their li'l home security camera, but the video has gone viral and it's sweet.
A kid trick-or-treating on Halloween goes up to a house in his costume with mom and sibling, encounters an empty candy bowl, and generously decides to put some of his candy haul in the neighbor's bowl for the next trick-or-treater.
Paying it forward.
