Not spamming you, this guy is a dude! He knows alot about snoring and writes in a way that is so honest it almost makes you laugh.

My wife had to cope with my stacks of books when we moved in together. She chose to develop a library-like system for organizing them. While I miss the soothing, cozy presence of books close at hand it does make it easier for me to find them, and I try to appreciate that. In this case, she chose to put her own effort into something that was important to her, and I agree to make an effort to keep the order and keep in mind how it benefits me too.

Hair in the sink is something he should deal with — it isn’t hard to clean up, and there is no redeeming value to that particular brand of messiness.

Those are specific little things. I would guess that there are other differences that cause friction at times. I suggest a book on dealing with different personality types called “Please Understand Me II” (skip Please Understand Me 1, the second book replaces it and is better). This book talks about our tendency to try to impose or cultivate our own virtues on our spouses and loved ones, and although it is only one of many imperfect models of personality I think it is really useful.
