Walking the Cat

Was walking my cat on a leash through an area of Westwood I'd never noticed before. It was full of lakes and bridges and greenery. As we walked over a bridge, the cat spotted something and leapt down a hill. It was a long leash, so I didn't lose her. 

At some point later on in our walk, a big German Shepherd spotted us and came bounding toward us. As it approached I said very sternly, "Sit!" and I think the cat said something to me like "Wow, you think that will work?" But it did. The dog sat. I looked at it's tags to see to whom it belonged and I asked the cat to pass me my cell phone so I could call the owner.
