I'm currently watching the dog who lives in the house across from my office. I think his name is Brian, and his interests include sniffing the air and barking for no good reason.
There's also a cat sometimes, birds in the tree by the window, a spiderweb in the corner of my window, the occasional bird of prey circling the site, and planes from the closeish airfield. I try to not watch the people in the house opposite doing their dishes. Feels a bit too voyeuristic.
It's a pretty great view, all told.
