My DD3 still amazes me. Today she requested to 'watch' a story in the car which was all audio. I countered with don't you mean hear the story which she quickly came back with "No, mommy. It should be listen to ..." This is the second correction this week and both times she was absolutely correct. I don't know why that was jaw dropping for me since this is the kid that knew proper pronouns from the beginning which was when she was 6 months but this seems so much more complex.
