I guess you could call an incident in the dog park last month a verbal altercation. I was kicking a soccer ball for Shadow to fetch. I had been kicking it toward an unoccupied part of the park. I kicked it again and noticed while the ball was in flight that a guy had walked into the area. I said "heads up." He didn't need to take any evasive action. I promptly said I'm sorry. He began bitching me out. I apologized again. He continued. When I had had enough I told him he could go ahead and [bleep] off. He really didn't like that. Somehow, that escalated things. I never said another word. A few of the other people in the park egged him on a little bit. I haven't seen him since, but some of my buds say he brings a stick to the park with him now.
