on being so angry I'm speechless

A guy in a Lexus in front of us threw a McDonald's cup out his window as he drove up my street. When we pulled up next to him, Nick said, "Stop throwing trash in my neighborhood."

Tell me why this man said, "Fuck this neighborhood."

"What?" I asked. 

"Fuck this neighborhood," he repeated. 

"Well, we don't feel that way," I responded.

"Well I do." He paused. "Thanks for telling me how you feel, though."

Nick and I just sat there in angry silence. As the light turned green and we pulled off, the man shouted something unintelligible at us. So brave of him.

I've never been so angry. Or so speechless.
