The doctor’s office felt sterile, but Amelia found herself grinning, a small, involuntary twitch at the corner of her lips. She tapped her toe against the linoleum floor, humming a jaunty tune under her breath. The receptionist had just informed her of the mix-up, revealing she had the medical history of one Bartholomew Higgins. Bartholomew, it turned out, suffered from an array of rather peculiar allergies.

“Well, this is a lark,” she mused aloud, her eyes sparkling. She leaned forward, resting her elbows on the counter, and asked, “So, Bartholomew’s allergic to… what was it again? Dust bunnies?”

Amelia imagined Bartholomew Higgins, a man she'd never met, frantically sneezing at the sight of a fluffy duster. The thought sent a fresh wave of amusement bubbling up inside her.
