How would you interpret ‘today of all days’ here? She had come a half hour early, today of all days, and caught me red-handed. The broad, canvas-bound notebook in my hand. I’d been wondering how to set that cotton duck to flame; the army tends to manufacture indestructible things. Stamped plainly across the front: “Potomac Academy.” She could probably see right through to the naked figures inside, as if catching me with an eight-pager. I may have blushed. How would you interpret ‘today of all days’ in the context? Thanks! And it’s from The Lacuna by Kingsolver.
