Rachel's eyes lit up. "What kind of exploration?" she asked.
One day, while organizing a new shipment of books, Lena stumbled upon a novel that caught her eye. It was an older book, with a cover that seemed out of place among the newer titles. The title, "The Art of Exploring the Unknown," sparked her curiosity. She had never seen it before and couldn't help but wonder what it was about.
Over the next few weeks, Lena and Rachel embarked on small adventures. They took different routes to work, tried new foods, and even attended a lecture on a topic they knew little about. Each experience was a small step out of Lena's comfort zone.
