Speaker watched her closely without giving indication of it. Oh, she didn't like his turn of phrase, did she? That left him with a bit of an opportunity.
While she browsed, he wandered away from her, to the edges of the stalls, and wove a bit of fire together. He held it down at his side, palm hidden from her so that she would not see it as she approached.
"Oh, ah..." He gave the dagger a genuine, critical look then told the absolute truth with the first real smile he'd worn in front of her. "As it happens, I wouldn't know a decent dagger from a butter knife! Though..."
He raised his hand, and a hummingbird of flame burst forth from it. It flitted about between them, squeaking out a tune of random notes. "Let there be no confusion. Forgetting one's responsibilities is sometimes necessary, no? How will we witness Her will if we are always looking down?"
The hummingbird dove down, straight into the dagger, where it burst into a tiny flower of sparks. The flower held in the air for a space of moments, then died, leaving behind a red, etched hummingbird upon the blade. A blessing.
