One evening, Sarah decided to take a walk after a long day at work. As she strolled through the park, she noticed the sky turning shades of orange and pink as the sun set. Lost in her thoughts, she realized she had wandered farther than usual. She checked her phone to see the time and noticed her battery was almost dead. Not wanting to get lost in the dark, she quickly retraced her steps. As she neared her apartment, the streetlights flickered on, guiding her the rest of the way. It had been a peaceful walk, and she felt refreshed.
