What can we learn from the way a character describes themselves?
Narrator name: Their given name.
Nickname: What do people call them?
Expansions: Your choice of extra details. But notice that Ort doesn’t describe himself physically. Instead he expands on meanings of his name—short, zero, nought, bum—that all reinforce the sense that he is somehow small or insignificant.
Try to bring the description to a conclusion that feels meaningful (not just an arbitrary detail). Ort does this by returning to his given name. Look at the examples below for other ideas.
