I now walk the Silver Lake reservoir holding tennis balls and waiting for a dog

You were walking the path around the Silver Lake reservoir on Sunday morning with three tennis balls in one hand and an expression of very deep concentration. I was behind you wondering what the plan was. Then a dog came out of nowhere, you threw one, the dog caught it, and you laughed so loudly the whole path turned around. It was a very good plan. I have walked the reservoir with three tennis balls since. No dog has come. I am still carrying them. I am the plan.
