It was extremely obvious I was waiting to pass. I gave them plenty of time to say their parting verbage, but instead of doing that, the guy angrily tried to shoo me away. By then, there was no need to lower my window and plead with them to move it along. His disdain for common courtesy heightened the situation as well as my response. He was aggressive, shouting and close to my vehicle as I passed. This is not the time to lower your window to have a conversation. He couldn't see me or know how many others were in my vehicle, so I played that card in my favor.
