At 11:30 one night my father insisted on going out to check the hogs. Mom was already in her nightgown. She put on a long coat and some shoes while Dad was putting on his coat. Off they went, walking the streets for about 45 minutes before Dad finally said, "I think they will be alright." They had not had a farm or hogs for 50+ years. Very shortly thereafter, they moved to a care facility.
