Pet Peeves with the spouse in the bathroom

When it comes to arguments/disagreements with the spouse, I believe there is only one root to the problem.  It's not the bills, the work schedule, or guys night out.  It's the bathroom!  Trust me, I know this.

I don't have any research or have a bachelors in Bathroom, but I certainly know the feeling when you walk into a bathroom and you see some one's  mess on the floor, sink, mirror, wall, tub, etc.

What's my BIGGEST pet peeve in the bathroom?

When a roommate/spouse/whatever, gets on your case about a sock on the bathroom floor, while he/she has a pile of clothes building up on the floor just a foot away.  It goes under the "do as I say, not as I do", which I can't stand.  Just my two cents from previous experience.  Everybody keep the little room clean, and your relationship will be ten times better.
