The primary purpose of metaphor and simile is to compare two, unlike things.

Both metaphor and simile are the figures of speech which are used while comparing two people, characters, ideas or subject. A metaphor is a hidden comparison between two things which possess at least any one idea common to each other. The things may be completely different from each other but would have either one characteristic in common to them. Simile, on the other hand, is the direct comparison between two things. It compares two things by using ‘as’ or ‘like.’ These two figures of speech are used in literary works which enhances and adds the beauty of the work.

s a child, Dede is always smiling, trying to please.  She is intelligent, inevitability and from a young age her father depends on her to "help with the books".  Dede volunteers to stay behind with her parents so her sisters can go to boarding school (Chapter 1). Though she is attracted to the rebel Lio, Dede is silent about her desires and loses him to her sister Minerva.  In a furtive attempt to assert herself, Dede burns Lio's letter asking Minerva to flee the country with him, but she cannot allow herself to the inevitability of the life expected of her.  She marries her domineering childhood sweetheart Jaimito, and finds herself "already beginning to compromise with the man" even before they are wed.  Dede knows that "if she...(thinks) long and hard about what (is) right and wrong", she would join her sisters in revolution, but she does not because her husband forbids it (Chapter 5).Dede finds her voice only after her sisters' deaths.  In the immediate aftermath she screams her defiance to the SIM, then takes charge of the girls' funeral arrangements and raises their children.  After several years she leaves Jaimito and establishes herself in the business world.  Dede retains much of her old self in her new life, however.  She continues to achieve, winning prizes yearly for "the most sales of anyone in her company", and sacrifices her privacy to keep the memory of her sisters alive (Epilogue).
