The house on mango street ( Rafaela who drinks coconut and papaya juice on tuesdays)

In this chapter, Esperanza talks about a woman, Rafaela, who gets locked up in her house whenever  her husband goes out. The reason as Esperanza puts it is the husband is afraid she will run away since she is too beautiful to look at. On some tuesdays whan Esperanza passes by Rafaela's house she is given a dollar from Rafaela to get her either coconut or papaya juice.

This chapter was pretty interisting to read, but what it dosn't really tell us, the readers, exactly why this woman drinks papaya juice and coconut juice.
