What is that one small thing that your significant other does, something that should be so insignificant at to not matter, that really irritates you?

For me it happens in the car. Whenever the car stops, and it matters not why or for how long it will be at a standstill, she will reach over and turn the A/C off. Then, worst still, she will roll down the window to “let the air in”. She says it is because she thinks the engine is working too hard when it is just idling with the air on or that it is so nice outside (yeah, it was inside too until you changed it).

I put it down to perspective, she thought we bought a car with air conditioning, When actually we bought an air conditioner you can drive.

We have been “discussing” her “idiosycrasy” for about 40 years now to no avail. As I said minor but annoying.

What is your complaint?
