I have noticed a lot of older stories the main protagonist has no name or their name isn’t revealed unless the speaker is addressed by another character. And then sometimes when someone address them, they aren’t call them by name. They’re referred to as “Sir or Ma’am.” I noted to be especially true of stories told from first person experience. I guess it would seem awkward for the protagonist to say, “My name is John Smith, I live down on Cranberry Lane in a town called Louvre. Let me tell you what happened to the me the other night…..”
These stories are interesting for they leave us with more questions than answers. The mystery is the beauty.
