Mommy-daughter first verbal battle

Bea and I had out first 'heated discussion' a few days ago! I picked her up from daycare and it was a beautiful day, so we headed straight for the park. She was so excited, belting out "slide!" and "wee!" upon seeing the playground. But...when I got her out of the car I realized she had a dirty diaper and, alas I had not brought the diaper bag. Oh no! Trying to get Bea back in the car was a feat for an Olympian- she was totally hysterical. She cried all the way home and all the way through the diaper change. Finally she calmed down, but when I tried to put her back in the car to go to the park, she became hysterical again, kicking, screaming, tears, snot, the works. Finally, I put her down on the driveway and we had are first 'fight':
Me: Bea, do you want to go to the park?
Bea: (through tears) Yes!
Me: Then you have to get in the car.
Bea: (crying harder) No!
Me: If you want to go to the park, you have to get in the car.
Bea: Park! (looks at the car) No no no no no!
Poor girl can't quite reason through this one yet. I managed to get her back in the car (a miracle considering all the flailing limbs) and to the playground, but she was pretty annoyed at me for a while and didn't want to do anything I suggested. So it starts!
