"This hat is ineffable," he said.
She had to agree. The way it contoured his head, at once enlarging and somehow, amplifying his cranium, struck her as near impossible. Unexplainable.
"Might I try it?" she asked.
He agreed, but only on the terms that she have a hat of her own. There was a flash as the man spun in a wild, enthusiastic gambol. Light emanated from atop his head. She held up her hands to shield her eyes and something dropped into her lap – a brand new hat. She picked the newly formed hat up in her hands and examined it closely, before placing it on her head. There was something wonderful about the hat, at once masterfully complex and wonderfully benign.
The hat was indeed ineffable, she decided, faceted as it was to astutely represent the whole of the deftly transcendent and the undeniably simple. How like life, she thought, as the man bounded away, hat both askew and not askew - a multifarious and crystalline explosion, reflected and refracted in impossible planes and colours through infinite refinement, on simplistic foundations. She adjusted the hat on her head. A passerby smiled at her.
"Yes," she returned the smile. "It's ineffable."
