Thomas is my friend, I guess, but we don't have much in common. He's not a good runner like me. He has a real long body, but short little legs so he walks like a caterpillar and Mom and I have to walk slow so that he can keep up. He's never been camping, didn't go to puppy school, and is unemployed, so we don't have much to talk about. Mostly I just pretend he's not there, and I'm not sure he's noticed me yet either.
The best way to cheer is to stand by the side of the road, and then sprint out onto the course when you see your dad run by. That way you can bark at the top of your lungs how proud you are of him, and you can also clothesline a few other runners with your leash. If you do a good job they will trip and die, and your dad will be more likely to win. That's called being supportive.
