The school year had been particularly challenging for Ms. Chen. Burnout had settled in, and she was starting to question her choices. She looked at the blank canvas she’d brought home, planning to work, but she was finding it difficult to find motivation.

An email. A digital greeting card. It was from one of her students, now in university. It showcased a painting, inspired by her classroom. The text read, "Ms. Chen, thank you for showing me how to see the world. I hope you're doing well."

She stared at the image, her eyes widening. She blinked away the moisture threatening to spill over. Her fingers trembled as she clicked "reply." She felt a flicker of the passion she thought she had lost.
