Watching Sound of Music with Ella, who is four. We get to the scene where Maria comes to dinner and the children have left a 'gift' on her chair:
Ella: Why did she yell?
Jenny: She sat on a pine cone.
Ella: No, a porcupine.
Jenny: It wasn't a porcupine, it was a pine cone.
Ella (becoming passionate): It WAS a porcupine.
Jenny: No --
Ella: I SAW it MOVE!
What could I say? It did move. . .
