"Did I throw my cell phone at you?"

So I issued a citation to a vehicle and later the citizen found me. (Not at all hard since I was working in a small neighborhood..with bright flashing lights on my vehicle) Anyway she came up to me and I explained what the ticket was for. In between the expletives, I did recognize the words..and, the, you are, and go to. She finally went back to her vehicle, out of breath and out of short descriptive sentences. I would say..hmmm..about 10 minutes had past and I see the same woman, in her car, in my rear view mirror. Of course this is where I have a little fun. I drove around for 5 minutes with complete randomness. I finally pulled over. She came up to me window, cracked open 6 inches, and she started to apologize. After her apology, she asked one question, "Did I throw my cell phone at you?" I paused, trying not to laugh..at least..on the outside. I then said, "I did not hear anything hitting my vehicle."

How can someone be so angry, in a span of no more than 10 minutes, and forget if they did or did not throw their cell phone at me? The world may never know such minor things.
