In '' a visit of charity,'' how does the nurse choose the room where she places marian?

The nurse chooses the room by chance. First, she asked Marian if she had any acquaintances there. Then, she just brings her into a random room, with a remark that there are two old ladies in each room. This leaves the impression that the inmates are nothing more than mere numbers. They are not regarded as persons, but as irritating and grumpy old ladies. This is a bleak, grotesque, and unsympathetic world of elderly people who get visits only from people like Marian, and she does it not because of compassion, but because she wants to gain some points for her charity work.
