Yes, I knew someone like the author’s grandmother. It was my own grandmother who passed away recently. The intense sense of loss is very heart-wrenching as I spent almost fifteen years of my life with her. OR No, I have never known someone the way the author knew his grandmother. Thus, I have never felt the sense of grief presented in the story.
