I am a tree and very sad nowadays because those people who love me in the past are going to cut me soon. I am feeling heartless. They used to sit beneath me under my shadow, but now they have become very selfish. These are the people of my village who don’t value my presence now. Have they forgotten the time they used to spend enjoying my existence? I know that I am old now, but what will happen to my branches, my fruits and my flowers? They are doing this over the small conflict of their family because they want my land. How could they do this to me?
