cONCEPT!
Self- aware epithets, u know those.... those things where for some reason you thought it would be evil to like use a normal name so instead u amade up a naem and called ur perfectly well-named character like "the twenty year old brunet" or smth equally unnecessary? it's! ok if u do that!
but! i happen to thinkg that, if you want to do that, you can do it, BETTER, with ur narrator NOTCING the epithet!!!! so it would be that the narrator refers to 20yo brunet but is struggling to think of how to even refer to him, b/c... confusion? or smth? idk man. anyway. so it would go... "this... this 20y/o, 20, y, o, growN MAN," you feel?
idk f that makes snes I'm tired and tomorrow ill probabhy delete this thing but now it's smmmmmmmmmmmmmart
