I'm prepared to be told I am so here goes.
We have long pile carpets so doors don't "swing" as such. I tend to just push a door and then walk away, To be honest, it doesn't bother me and its an effort to remember as the first 20 years of my life were specifically spent leaving internal doors open so the cats and dogs didn't start howling at closed doors.
"DH" has a thing about doors being made to be shut. The one that drives him nuts is the one to the laundry cupboard. I put laundry in the basket and just push it behind me - and its always slightly ajar. This for some reason gives him the rage.
He's now threatening to take the door off the hinges if I don't learn to close it because there's no point in having it. Except it is closed its just off the latch.
So,
AIBU - I should make the effort to close the door even though its not something I actually think or bother about
AINBU - its a bloody door
