Shared Feelings

Even a couple times Jonas father has broken a few rules, some not as important as the other and his mother who was a court and stuff didn't scold him yet was smiling too. I think that it's kind of cool that they are able to share ones feelings with the other without getting upset with each other but they can understand and help them, instead of the feelings being bottled up inside. How are they able to break the rules without being caught sometimes?
