3 going on 13

Situation:
Ellie getting ready for preschool. She puts on her skirt and we proceed with the following conversation.

Ellie: "Mom I want to wear pants with my skirt."
Mom: "Ellie you don't wear pants with your skirt you wear tights."
Ellie: "But Mom, all my friends wear it like that."

I was in complete shock. I didn't think I was going to be hearing anything like that until my little girl was 13 not 3!

PS. This kitchen window sill is where Ellie waits to keep on eye out for her Dad's daily return home from the office. Sometimes she is waiting for a VERY long time....as in she starts looking out for his return as soon as he leaves!
