Several times this month I've found our nativity's characters all bunched together under the roof of the manger. I then take the time to spread them all back out again in their appropriate spots according to story, and mere physics.
I finally asked Jo why she keeps piling them on top of each other and she responded,
"That's where the party is."
"Where?"
"There.", under the roof of the manger.
I think she gets it.
