The heat of the day seemed to press down on Ethan. His legs felt like lead weights as he navigated the cluttered yard sale. He blinked, fighting to stay focused on the task at hand. His head throbbed. He’d barely slept last night, tossing and turning with worry. He shuffled past a collection of chipped porcelain dolls, each face staring blankly. He was about to give up when his gaze landed on it.

There, wedged between a tarnished silver picture frame and a box of old VHS tapes, sat a familiar face. It was Mr. Snuggles, his childhood friend. He let out a soft groan. It was just the sight of the bear that brought back such vivid images of his past, making him yearn for the blissful oblivion of unconsciousness. He felt the pull of the past and the exhaustion of the present collide within him.
