The email arrived like a death knell. Sarah stared at the subject line: “Important Company Announcement.” A chill ran down her spine, a sensation she hadn’t felt in years. The font seemed to shift, swimming before her eyes.

She remembered the excitement she felt when she first accepted the job, straight out of college. Her desk used to be adorned with posters and pictures, a reflection of her vibrant spirit. Now, it was bare, reflecting the emptiness of the news.

She stared at the photo of her college friends, the one that had been on her desk all these years, a soft smile tugging at her lips. The image seemed to shift.

She felt a tightening in her throat, a familiar sensation when she remembered her past, and everything that had come to pass. A sudden craving for the familiar scents of the office, the comforting clatter of keyboards, the voices of her coworkers.
