Keep going, I said, and you did

You were throwing a blue frisbee to a dog in Pole Mokotowskie on Sunday afternoon and every time the dog caught it you bowed to the whole field like it was a show. I was on a blanket with a book, pretending to read. On the tenth catch the frisbee landed on my blanket. You came to get it. You said, sorry. I said, keep going. You did. By the fifteenth catch I had put the book down. The dog bowed too. I was not asked to.
