Great idea! It appears to be a reasonably achievable task with this example because there is a way for Heather to show respect for her H's opinion about son completing tasks by starting the tasks earlier at night while also achieving her goal of getting her son to bed on time which is also important.
This is where she has to do some extra work to ensure the tasks start early enough that they can be done at the appropriate bedtime but that extra effort would show her H 3 important things 1) that she listened and respected his opinion (She could even say out loud to son, with H there, we need to start this earlier because your father is right that you need to learn to complete tasks that you start), 2) is taking action to support his views (make the tasks start early or do not start them at all if there is not enough time to complete them by bedtime - another good lesson:)) and 3)that she still respects her views enough to not back off and to do "extra" work to ensure the importance of getting enough sleep is recognized. I think her husband will respect her for sticking up for her views in this manner. FWIW many doctors and educators have been writing about the serious issue of too little sleep in school children.
Heather,
Good Luck with all of this. You "sound" tired. Take care of yourself too
