I don't get this but I want to remember it happened so

I'm sitting here singing "All God's critters got a place in the choir" and suddenly I can't because I'm crying and I don't know why. I don't know what this song ever did to me.

My only association with it is that it was a favorite song of my kids and every institution they were connected with, despite their rather militant atheism. So am I having a bout of nostalgia? Could be, though this is the only symptom.

Sure is an optimistic little song, though. And also cute.
