I think there are many things that are different between cultures. Do I really need to highlight those?
The people in the article certainly seem to have issues that are very common among all marriages. I'm saying, it is the little things that cause those problems to arise, that are different. I'm not black, and I don't know how kids are brought up in relation to their values on marriage, women and chores around the house, or handling house finances. But, I'm sure that certain things are valued more than others in each culture, and that certainly makes circumstances different in dealing with the umbrella issue at hand.
However, you're right. This particular couple seems to have much more similarity to everyone involved in marriage.
