I’m writing a story about a woman who becomes a graffiti artist in the suburbs, and now I spend my time thinking about what I would do as a graffiti artist. Inspired by Banksy's rats, I might make a lot of squirrel art. Dress the squirrels up and have them deliver critiques. There are a lot of squirrels around here, including a family of black squirrels whose base of operations is quite close to our house. Once I was walking my exercise loop and became worried that a black squirrel was following me, but then I realized there were just a lot of black squirrels. So then I worried that they had organized surveillance.
