TheDad just left for work, after whipping Little Brother into an anticipatory frenzy about the evening's activities and the likelihood of collecting a lot of chocolate.
(Little Brother's teacher will not be pleased, as I'm sure the other 27 kindergarteners are similarly excited.)
So Little Brother bounced over to me and said, "I'm going to say 'Trick or treat! Trick or treat!' That's like 'please' in Halloween! And then you say 'thank you'!"
