The worn map lay spread across the table, the faded ink hinting at adventures past. Robert traced the route they'd taken on their cross-country road trip, a smile tugging at his lips. He could almost feel the sun on his face, the wind in his hair, the endless stretches of open road.

He remembered the time they’d gotten lost in the desert. He recalled the moment of panic, the eventual relief. He had been the one who had navigated them to safety, relying on his instincts and his knowledge.

He’d been chatting to Chris just last week, and he had mentioned the road trip. Chris had asserted that *he* had been the navigator. Robert's expression fell. He felt an odd sting. The desert, the road, the whole trip… it felt different now.
