A morning disagreement

I was talking on the phone when Larien stomped into the room with a scowl creasing her brow.

"Inwe says it is winter. I say it's fall. She's not right."

My sister laughed loudly at the other end of the phone line. I ignored her for a bit to address Larien's issue.

"Larien, Inwe is right. The first day of winter was last Friday. It is winter."

The scowl deepened. She turned to join her sister in the sunroom, but she added this bit, "I'm angry at Inwe."

How many three and five year olds debate which season it is? Huh?
