In my opinion, the mother said this to the girl so she could develop strength in herself. This line depicts the kindness and weakness of a girl. Feminism is one of the biggest qualities that a girl possesses. However, the girl’s mother wanted her to be strong so that no one could exploit her. She warns her daughter that her in-laws might harass her as she is a girl when she gets married so she has to prepare herself and become a courageous woman to handle any such situation in future.
