Beautiful answer — or, perhaps more exactly, a beautiful reply, since it's a way of replying to a question ("What is a...") with another question. What, indeed, is a person?! I don't know how to define "person," but I have a general observation about people, which is that each individual does tend to frame their own questions about life, and once they become aware that they're doing so, they may choose to reframe some of their questions. With those reframes, they may begin to find better answers, even if the answers they find are not the ones they originally sought.
