The change that came in the grandmother's evening schedule was that she started collecting the women of the neighborhood. This change is mentioned in the story "The Portrait of a Lady" by Khushwant Singh.

**Explanation:**

In the story, the grandmother is portrayed as an old and traditional woman who follows a fixed routine and is not very social. However, after the narrator's grandfather passes away, the grandmother undergoes a change in her evening schedule.

Before, the grandmother used to spend her evenings sitting alone on the verandah, lost in her own thoughts. However, after the grandfather's death, she starts collecting the women of the neighborhood in the evening. This change is significant because it shows a shift in the grandmother's behavior and her desire for companionship.

By collecting the women of the neighborhood, the grandmother is able to engage in social interactions and have conversations with others. This not only helps her overcome her loneliness but also provides her with a sense of community and support. The women of the neighborhood become her companions and confidants, and they offer her solace and comfort during her grieving period.

Furthermore, the act of collecting the women of the neighborhood also highlights the grandmother's role as a leader in the community. She takes the initiative to bring the women together and create a space where they can gather and share their experiences. This demonstrates her strong personality and her ability to connect with others.

Overall, the change in the grandmother's evening schedule from sitting alone to collecting the women of the neighborhood signifies her need for companionship and her willingness to embrace social interactions.
