He leaves any and all doors/drawers open after getting what he needs out of them. Kitchen cabinets, the dishwasher, the microwave, bathroom vanity, closets, dressers, night stands.. I can always tell whether or not he's home when I walk through the front door. It will look like our kitchen is about to be ransacked.
I've called him out on it like twice - when I first noticed it was a trend and a time after that - and he was genuinely surprised. He was like, "you're messing with me, you opened some of those." Nope. 7 kitchen cabinets and drawers apparently had to be opened for you to make your snack - all you, babe. He sincerely apologized, but here we are 4 years later and I still just follow him around closing cabinets and drawers after he leaves the room. It's too comical to fight over, and it really doesn't even bother me terribly, so I just don't bring it up.
We've finally worked out after 13 years together that sleeping in the same room as each other just doesn't work for us and we are happier and healthier sleeping in separate rooms. Means we have to prioritize intimacy, but we are happier and saner sleeping in his and hers rooms. He snores and likes to watch movies on his iPad until the middle of the night and I wake up if a mouse rolls over two blocks away - years of sleep deprivation have taught us both that a good night's rest make us more loving partners to each other.
