The social worker is called by a nurse because the couple does not have health insurance. The social worker is aware that this is an Amish couple and knows that generally Amish people do not believe in or accept what they consider to be welfare. When the social worker meets with the couple, she confirms that they are not seeking assistance in acquiring health insurance; she helps them plan transportation home, and she assists them in reaching other members of their Amish community who, by tradition, provide financial and other assistance to their own people.
