This is a really interesting thread that's actually bringing up a lot of issues for me. But first, a thought from my BF: If you're not used to moving furniture, it's really hard to remember that floors are easily scratched. BF has a lot of experience moving things, and as I was telling him Nancy's story, his first reaction even before I finished the story was "He scratched up the floor, right?" So it's not something that you might figure would happen unless you've had experience moving things. We even scratched our floor recently, though the piece of furniture we were moving was on a thick moving blanket. Still managed to scratch the floor! Also, this sounds ridiculous, but maybe your DH didn't see the scratches, either--sometimes it's just hard to see them until it's too late. (I put big black dirt streaks on our kitchen floor recently and didn't see it until the day after I had done it.)
Really long post here....
Second, I am definitely a perfectionist, too and I know I would have had the same reaction. It got me thinking that women have traditionally been responsible for keeping house. A lot of women now also work outside the home, too, but I think that we feel that our houses still ought to be as perfect and spotless as our mothers (theoretically) kept house. At least I know that's what's behind my perfectionism with house cleaning. On the other hand, we ALSO want our DH/BF/significant others to share 50-50 in the household chores, but they had damn well better come up to our standards of perfection, too!
I find myself constantly battling to not be so uptight about household perfection--it doesn't really reflect who I am or what I am like as a person. Yes, I want to live in a nice place that I'm proud of, but if the dishes get washed later in the day, rather than the minute that breakfast is done; if the bed is made after work; if things aren't as organized as I would like them to be--well, it's not going to really matter and noone is really going to care except me. I still lose my temper with the BF over all those things--his cleaning schedule is "different" than mine and it drives me nuts. On the other hand, if I want him to take that 50% responsibility, then I have to let him do it his way. I guess that doesn't apply directly to the scratched floor problem, but your discussion just brought this whole thing to mind for me.
