We aren't fighting!

While I was in te bathroom this morning I could hear my lovely children on the other side of the door going back and forth saying, 

"No!"

"Yes!"

"No!"

"Yes!"

"No!"

"Yes!

Over and over again. So like any good mother I called out, "It sounds like you guys are fighting. Please stop!" (It was still early in the day, so I wasn't too frustrated with them yet, thus the please.)

Rachel's reply was, "We aren't fighting, we are arguing." 

She was right of course, but it just kind of stunned me to hear that from my 3 year-old! She is such a smarty-pants!
