In The House on Mango Street, Esperanza's concerns in vignettes one through three mostly relate to her ideas about belonging.  In the first vignette, Esperanza and her family dream of owning their own house, one that will allow them to realize their dreams and escape the taunts of neighbors and the greed of landlords.  In the second vignette, Esperanza describes the varying hair types of her family and suggests at the end of the vignette the comfort that she feels when sleeping next to her mother.  In the third vignette, Esperanza talks about the separate world of boys and girls and the distance she feels from one of her sisters because of their age difference.  She dreams of the day when she will have a best friend of her own.  In all three vignettes, the line of commonality is the sense of belonging for which Esperanza is continually seeking.
