Dolly is now happily listening to a Dave Brubeck recording; I thought she deserved it. Sweetie has been listening to the ball game in another room. (ahem)
A downside to sleeping with the windows open - there aren't many - is that you might hear something unpleasant. Last summer I'd sometimes hear chittery-chattery noises, and would imagine some unfortunate squirrel or rabbit being caught by a predator. I always felt bad.
I heard it again a couple of weeks ago and thought I'd try and find it on youtube. Well! Turns out it's just a raccoon noise, and nothing so horrible as I'd been imagining. What a relief!
