In the It's a Small World category:
I kid you not, the following discussion took place, without any prior knowledge about our discussion here and completely unprovoked by me, at out dinner table tonight:
dd14: Which milk is which?
dd16 (pointing with her head and her gaze because her hands were full): That's the skim and that's the 2 %.
dd14: See, I could tell what you meant because of my mirror neurons.
dd16: Your what?
dd14: My mirror neurons. They not only allow babies to imitate people's expressions, they also help you *interperet* the meaning of other people's gestures.
Really, I'm not kidding. At this point I walked in with "Did you just use the words 'mirror neurons' in a sentence?"
dd14: Yeah. (gives me the so? what's the big deal? look)
/me proceeds to explain our discussion here. Then I ask, "So, what did you learn? Is the smile inborn or learned?"
dd14: "Don't know. The article didn't say."
There you go, FoLCs, life imitates art, at least at Happy's house.
