Why is esparanza disappointed in the house on mango street

Esperanza is disappointed by the red, ramshackle house. It is not at all the dream-house her parents had always talked about, nor is it the house high on a hill that Esperanza vows to one day own herself. Esperanza is not only ashamed of her home, but she is also uncomfortable with her outside appearance, which she feels does not convey the true personality hidden insider her.
