Those are great too, but most people are aware of those, but are not aware of how important it is to share what's really going on inside us.

A lot of women have a tendency to hold things in until it comes out in anger or bickering. Instead of telling their husbands that they don't like when he puts his shoes on the couch when he first does it, and kindly ask hlif he can help her out by not doing that in their home, she holds it in and waits until it starts coming out through annoyance.

"Why do you always put your dirty shoes on the couch, it's getting ruined and I need to clean it.." and so on. (For example)

So practicing beforehand will make it a lot easier to share a household and stay married if little things are dealt with early, instead of them building up and the home environment becomes contentious, which is one of the most common reasons for divorce.
