Mr. Henderson stared at the anonymous gift on his desk: a brand-new, top-of-the-line fountain pen. He traced the smooth, polished barrel with a calloused finger. This felt… astonishing. The school janitor, a man named Bob, had once been one of Mr. Henderson's most quiet students. A troubled youth who'd only found solace in the school library.

His pulse quickened slightly. He remembered Bob's shy demeanor, and the way he’d always lingered after class, browsing books. This was utterly unexpected. He found himself rearranging the pens in his desk drawer, placing the new one in the most prominent position. Later, he composed a letter to his own daughter.
