why does esperanza agree that the flat is her home even though it isn't and its in worse condition than her own?

In this chapter, Esperanza wants to eat in the school lunch room, the canteen, because she is under the impression that "the special kids" eat there. To her, not returning home for lunch seems to be an exciting prospect. After finally convincing her mother to let her take her rice sandwich to the canteen, Esperanza's illusions are shattered when a nun makes her point to her house from the window and tells her she lives too close and cannot eat there again. Esperanza does not see a way she can conform to a society she wants to be a part of.
