Dear wife, you know energy costs have gone through the roof. And we live in a small terraced cordage with a front door, a back door, and one door in between, that is generally open during the day. When you go out the back door, why do you have to open it to the 90 degree position, and then wander off to see to your washing/garden/compost bin when a simple nudge back would accelerate its closing to a significant degree.
