The faded photograph, creased at the edges, trembled in Sarah’s hand. It was a picture of her eighth-grade class, a sea of awkward smiles and oversized glasses. There, front and center, was Mrs. Gable, radiating warmth in her signature floral dress. Now, here she was again, the same smile, the same gentle eyes, staring back from the school website. Her daughter, Lily, would have Mrs. Gable for third grade. A shiver ran down Sarah’s spine.

She found herself wandering the halls of her childhood home, touching the worn spines of old textbooks. The scent of dusty paper and forgotten memories filled her. She could almost feel the scratchy fabric of her school uniform against her skin, hear the squeak of the gym floor, the chalk dust tickling her nose.

Later that evening, as she helped Lily with her homework, Sarah couldn’t resist. "Mrs. Gable, huh? She's a wonderful teacher, you know. I had her too." Lily, engrossed in a math problem, barely looked up. "Cool," she mumbled, oblivious to the swirling vortex of echoes that had engulfed her mother.
