why didn't valli want to make friends with the elderly woman

Valli did not want to make friends with the elderly woman because she found her physically repulsive. She was put off by the woman's appearance, which included big holes in her earlobes with ugly earrings, and the unpleasant smell of betel nut that the woman was chewing, with betel juice almost spilling from her mouth. Valli's reaction was largely due to these distasteful sensory impressions and her youthful perspective, making her unable to relate to or feel comfortable with the elderly woman.
