So, we have a green space beside our little neighborhood that most of the 4 or 5 households let their dogs enjoy. I am out there with my old Golden Mollie, and have the tennis ball throwing stick because she still likes to chase the ball. Neighbors at the opposite end of the street are there with their fairly young Irish Setter, Penny. Mollie and Penny sniff buttholes, etc. and seem to get along. I get ready to throw the tennis ball and Mollie gets alert. Throw the ball and Mollie goes after it, with Penny dogging her every step. Mollie gets the ball, brings it back, Penny could not give a shit about the ball. I throw the ball again and Mollie takes off, with Penny right after her. Mollie wheels around and in a scene reminiscent of a Hanson brother from Slap Shot, barks/snarls at Penny. It was almost like I could interpret doggo: "I'm fetching my fucking ball!"
