SLOW DOWN!!!

So yesterday, I was bee boppin along to the dentist, a short five minute drive, checking out my teeth in the rear view mirror to make sure there is no lunch junk stuck in there. I still don't see why I bother to floss and brush right before I go, it deprives them of their job.
Well, as I was checking out the back of my throat in the mirror, I hear a "wock wock" (the sound I have assigned to play the part of the undercover police suburban) and looked didn't see anything (because he as in my blindspot). Well, I did look at my speedometer, and I do pay attention to my speed, and it is often too high, especially on that road, BUT I had just turned on that road, and couldn't have been going super fast. So I finally see the car and only look over because the window is down. He yells at me to "SLOW DOWN!!!" with very exaggerated facial movements, and scared me to death. In fact, I died right there on Union Street. I nearly wrecked after that and was obliged to drive painfully slow, with my speedometer reading a cool 34 mph (just for him) even though I know that my speedometer reads three miles over.
So my problems with the way this happened are:

1) I found his method a little too distracting, after all it was an unmarked car, and I am still not completely sure that it wasn't some kid who was in school last week. Except the "wock wock" was fairly convincing. Come on! He was being a little sneaky.

2) My speedometer was reading 40, and its possible that the three over thing went away, but I doubt it. That means I was really driving 37 mph. For real? Is that the protocol for two miles over the speed limit. I guess he was trying to scare me, and he did, but not from speeding.

3) I really think he thought that I was a kid. I mean I know I am 29, and look 15, but the windows are tinted dark, and you can't see the kids real well in the back. Not to mention its hard to be perfect at following the speed limit when you have three children who want things crammed into the back of your car. Of course, on that note, sometimes its hard to stay in your lane, or in your mind.
