The essay, a recollection of a childhood summer by the lake, was printed on a poster at the career fair. Ethan saw it instantly. He stopped walking, and stared. A sense of unease, a cold sensation, settled in his stomach.

The poster seemed to radiate an unnerving cheerfulness. He recalled the joy he’d felt when writing it, a long time ago. Now, it was just… a picture, a story, a faded echo. He turned and walked away, the noise and bustle of the fair seeming to fade into a dull hum.
