In England, we have certain spoken routines for children. For example:
Parent: What do you say when someone gives you something?
Answer: Thank you.
And here's another one:
Parent: What do you have to be to make Santa give you presents?
Answer: I have to be good.
But sometimes children don't give quite the expected answer. I was just watching a video of my granddaughter, Elsie, aged 2 years 10 months, talking to her Dad about Christmas.
Dad: What do you have to be to make Santa give you presents?
Elsie: I want to be a princess.
