My wife, to this day, shuts off the shower and then immediately steps out while water is still running off her soaking wet body, inevitably creating a puddle in the bathroom.
"Honey, why don't you drip for like five seconds, or even grab the towel and give yourself a quick dab before you get out?"
The first time I told her this she just stared at me for a solid 20s while her brain rebooted. But then her "never admit anything ever under any circumstances" instinct kicked in and she responded "wow are you really policing my shower habits?"
So anyway, now she knows better, but still does it because marriage is about compromise, or something.
