Little or no communication: After a tiring day at the workplace, most couples come back home, do a bit of this and that and go off to sleep. When the husband and wife work in two different industries, their areas of professional interest preoccupies them. So, when they get back home, one talks about one’s office schedule and the other, about a completely different schedule with different priorities and needs. Neither of them has any interest in what the other is saying. That is bad.
