All marriages have friction points, mainly because each partner has a way they always did things before they married and neither sees a reason to change that, even after a quarter century together. My wife sees Saturday as cleaning day. Get it done first thing in the morning. In my childhood home, Saturday morning was sacred. My mom figured Saturday was to be fully enjoyed without anything unpleasant intruding. Sunday morning is when you clean as Sundays are already arsed up with the next day being a Monday, anyhow.
Coffee tables are another area. I dislike more than one thing on a coffee table for display. My wife likes a lot of things all over the coffee table for display. And everywhere else. So do I as long as they are tacky movie memorabilia or antique cameras, but not on the coffee table. It must be something like a tasteful dish or tray and just one item only. Especially not family photos as those go on shelves or walls. Or plants. I have never understood the point of houseplants that aren't fresh herbs, outside is for plants.
Finally, there is the fridge door. I like mine plain. Empty. Beautiful. My wife doesn't. Guess who won this round like most of the others?
