After the hospital escapades, we went trick-or-treating with Paige the Angel and Kieran the Dragon. Since both are a little older than Buzzy, they had the concept down a bit better. Buzzy could barely keep up as they ran from house to house. Within a few houses, we figured out why.
Buzzy would dawdle a bit after the candy distribution, point out something interesting about the person's house, "Wow, scary pumpkin!" or "Wow, BIG cat," strike a few scary bat poses and then accept the extra candy that was stuffed into his bag. Nine times out of ten.
