When we are in a relationship, we often give up certain parts of us which seem to be threatening to the relationship. David loves motorcycles but Lisa is afraid of him having an accident. Lisa on the other hand loves dogs but David dislikes them. In order to be together, David has exiled his freedom loving part that wants to ride a bike, and Lisa has exiled her pet loving part that wants to get a dog. If there continues to be no room in their life for these parts, this can sabotage the relationship.
