Honestly I know this is minor but AIBU isn't just for the big stuff.
We live in a semi detached with a drive we can't use.
There's plenty of unrestricted parking on our street and the adjoining street. The only time it gets busy in our area is glorious sunny days and Park Run time.
There is enough space outside our house and next door's house for 3 cars to easily park between the two dropped kerbs. Next door has a large drive that they park one or two cars on.
There's a convention that they park one of their cars outside their house leaving 2 spaces for 2 of our cars.
So DH and I prefer to leave our cars there, visible from sitting room window.
DS has tended to park into one of these gaps if they're empty when he pulls up, but I think he should park a smidge further away and leave the old folk to have a shorter walk to the front door.
I've had a minor word with him but I think he's thoughtless on occasion and soon goes back to pulling into the nearest parking space.
Aibu to think he should defer to us?
