Its not just husbands and wives though. I've argued to the point of loudness about whether or not Paul Walker was in Scream. Who cares? Why did I make such a big deal of it? Pride; because I need everyone to know that I know a ton of stuff.
Its dumb. In any relationship you will screw up. Thats why its important to err on the side of being loving. You're only paying attention and being intentional like 10% of the time. So you better make damn sure that 10% makes up for the 90% your on autopilot. Of the 90% your on autopilot you're probably pissing someone off half the time. Some of your numbers may vary.
