Can't Fool Mother Nature

The conversation went like this:

Princess: Do I need to wear long sleeves today?
Me & Craig in unison: Nooo! It's gonna be HOT!
P: But it's the first day of fall!?
Me: Somebody forgot to tell Mother Nature. Go get dressed, you're late.
(She walks away) She has no idea what that means.
C: Yeah, she'll me ask on the way to the bus stop.
Me: Sorry 'bout that.
C: That's okay. I'll just tell her to ask you because you know Mother Nature better.
