A quiet moment, reviewing pictures. What I've noticed with my grandson is that, when we're out on a photo walk, he ignores the image playback while he's actively shooting and waits until he needs a rest break to review his shots. It's not anything I taught him, but it's refreshing to watch him develop habits that will serve him downstream when I have him shooting film more regularly.
