The quote reflects the idea that perceptions can be limited by superficial appearances. The daughter sees her mother as an elderly woman, focusing only on her external age and physical attributes. This viewpoint does not account for the depth and complexity of her mother's identity and experiences.
Moreover, the mention of "tiger lady" symbolizes strength, resilience, and inner power. If the daughter looked beyond the surface, she would appreciate her mother's fierce spirit and the rich life she has lived. This contrast highlights the importance of understanding personal histories and recognizing the inner qualities that define a person beyond their outward appearance.
