Logic of a 4 yo

On our way home from violin lessons, the precious dolly Amy was holding somehow slipped from her grasp and fell to the floor of the car. Immediately, there was weeping and wailing, "Dolly, MY DOLLY, MOMMY I NEED MY DOLLY, WAAAAAAA."

I'm trying to help Amy develop higher emotional intelligence--i.e. an ability to realize that dolly dropping to the floor of a car isn't the kind of catastrophic event one would think occurred given the current level of response. "Amy, stop!" I stated firmly. "Are you hurt?"
Amy: "No."
Me: "Are you dying?"
Amy: "No."
Me: "Did the dolly fall out of the car and get run over?"
Amy: "No."
Me: "Then WHY are you screaming?"
Amy: "Because I NEED my dolly now!"
Me: "Well, I can't get the dolly now, I'm driving on the freeway."
Amy: "But momma, if you just unbuckle me I can get the doll."
Me: "But I can't unbuckle you, I'm driving. If I tried reaching back and unbuckling you we'd probably get hit by a car--or worse yet hit a car."
Amy: "But momma, if you unbuckle me REALLY fast then I can get the doll BEFORE we get hit by a car."
Me: "Uh, no."
Amy: "Momma, please unbuckle me so I can get the dolly. I will be fast!"
Me: "I'd have to drive off the highway, stop the car, get out, give you the dolly, get back in the car, and drive back onto the freeway. Do you know how LONG that would take?"
Amy: "Oh please mommy, just STOP The car NOW and get me my dolly, I NEED my dolly NOW!"
Me: "Thankfully, we are only 5 minutes from home, you can wait five minutes for your dolly."
Amy: "But mommy, that's a really LONG time..."
Me: "Yup, long or short, you're going to have to wait until we get home for doll."
Amy: (long sigh) "OK, mommy."

Of course, by the time we got home, she'd forgotten all about the dolly and I was the one who brought miss dolly into the house and put her away.
