We have this judgmental way of looking at the idea of leaving a home or a family, and our society has reinforced this idea that if we "run away," we are "running away from our problems." In some cases, though, to face certain problems (in this case, two family members who are not mentally stable and who are not going to face up to their issues) the family members who are capable of facing reality must realize that leaving is a viable option. Some environments are harmful. As fellow humans it is our job to judge less and encourage more when others choose to remove themselves from harmful environments.
