You're Fired!

I was getting Anika ready for bed while Mary was down stairs. Anika wanted to read books in mom and dad's bed, I told her we could read one book, since it was so late. She yells down stairs to Mary:
Anika: Mom come up and read a book.
Mary: Ok, I am coming

About a minute passes and Mary hasn't come upstairs yet.

Anika: Mom come up and read a book or you're fired!
