Because they're silly, I've saved up all my Phantom of the Opera-related sightings for one post.

( proof )
A few weeks ago, we discovered a rat in the window birdfeeder. Yeah, I know that's bad and stuff, but they haven't got in yet and we're not refilling it. I just keep forgetting to take it down. Because they're kind of cute. And they come in pairs and freak out the dog. He just jumps up and down in front of the window all night. It's hilarious. But also annoying. The cat has figured out she's never gonna get that, and doesn't take much notice.
In fact, the first night one of them came, the animals didn't notice it at all.
( the rat, and Kate not noticing it )
One night Mr. Darcy was so annoying I had to get up and close the blinds. But first I looked at the rat. It was a different one, not the injured one here. Instead of running away, he looked right at me. I touched the glass, and he put his nose where my finger was. I moved my finger and he followed me.
I think I have a friend.
It's really hard to think of them as pests.
