"Don't Argue With Me"

This morning while Jaida and I were eating breakfast I was watching her take really big bites of cereal.
"Wow, you are taking huge bites of cereal," I commented.
"No I'm not!" Jaida says as she furrows her eyebrows and gives me a look of death.
I calmly reply, "Jaida, you don't have to act like that. I wasn't being mean I was just making a comment."
With the same look of death and furrowed eyebrows she curtly replies, "Don't argue with me!"

I ducked my head and hid my smile.
