Defiance in the first degree

This morning Ellie was walking around with a snack cup of cereal. She started dancing and accidentally spilled some. I said "uh oh, we better pick it up" 

"No!" Was the response

In tried gently coaxing her but she was adamant.

"No!"

I finally said "you need to pick this up with me our you're going to get a swat."

Her response?

She walked over to the spot where she had spilled and dumped her remaining cereal.
