This is a personal response question. The answer should reflect a thoughtful and constructive attitude. Below is a sample response.
If I had a friend like Meena, my attitude towards her would be one of patience, empathy, and positive support. Instead of getting annoyed or avoiding her, I would try to understand the root cause of her unhappiness and negativity. I would make an effort to listen to her problems without judgment.
I would not argue with her pessimistic comments but would gently try to show her the positive side of things. For example, instead of just stating that the day is beautiful, I might point out a specific beautiful thing, like a flowering tree, to engage her senses. I would continue to invite her to do things and be a consistent, positive presence in her life. The goal would be to help her, not to change her overnight, by showing her that there can be a different, more positive way to view the world.
