Stuck

The sibling thing again. Eek.
This morning, Coco was doing "Eeny, meeny, miney, mo" (or however it's spelled).
Obviously, since he just learned it, he keeps getting it wrong. And Madge jumps in to "correct" him. But with that "you idiot" undertone - hell, overtone.
And again I'm stuck. She obviously doesn't know all the times we held our tongues when she erred in the process of learning. How could she? We held our tongues. So she seems to think that all we ever do is tell her she's wrong (or right). The uncommented-upon things are non-events on her horizon. As a result, she thinks she's just doing to (with) Coco what we did and do to (with) her.
He deals with it fairly well, though. And she feels bad when she makes him too upset, so I should just keep out of it.
