Prompt from sirensbane: Telescope. I'm away this weekend, so they'll probably be a touch short the next few days!
"The stars are amazing up here, Holmes." Watson turned away from his telescope and laughed. "Not that you care, I'm sure, but I enjoy seeing so many constellations in the sky. The skies over London are never this bright."
"My knowledge of astronomy may be nil, but I do still enjoy the view, Watson." His eyes twinkled with the shared joke. "You are always welcome to bring your telescope up here."
"Thank you, Holmes." Watson turned back to his telescope, staring up at the stars above. Once, they'd brought back memories of his time in Afghanistan, and the stark beauty of the stars in the desert sky. Now, it made him think of other nights like this, in the small country cottage Holmes had retired to, and the thought was always enough to make him smile.
