In the nineteenth century,at this period,women were the weak group of people so they usually didn’t have much freedom and choice to pursue their happiness.In fact,they were mostly dominated by their husbands and thus lived in a constrained way,which makes those women miserable throughout their entire lives.Nevertheless,in Mellissa Hardy’s story “The Heifer”,the main character,Aina,was a strong,independent,and adventurous woman who dared to strive for her life; unlike many other women,when Aina wanted something,she went after it.In this way,she should be considered as a hero.Her actions of starting a new life in Canada and killing her husband were just like an adventure which could prove us that she was a hero whom we should admire for her courage in pursuit of her own happiness.
