The Therapist<br>The couple had been fighting a lot. They went to a therapist to talk through their issues. The therapist helped them talk about things more calmly. They were feeling more optimistic about their relationship. They had the tools to work through their troubles.
The couple had always been a couple.
Children are born without mates. there is no way the couple could have always been a couple. The system seems limited by the text and lacks basic understanding of human development.
