A piece of art doesn't have to be a piece of art for everybody. It does not have to cause feelings in everyone.
Art doesn't have to be eternal. There could be something that works as art for a few people for a few weeks, for a lot of people for a hundred years, for one person for a lifetime, for a small number of people for a thousand years. There are all sorts of levels.
It is always a conversation, even if there is only one person involved in the conversation. You might make art as a conversation with yourself.
