Arya’s playing with her dad. She’s a shopkeeper:
Arya: O-oh, Daddy’s coming
Sanj: Hello shopkeeper. Can I have grapes?
Arya: of course.
Sanj: Very good customer service. Can I also have some lemons.
Arya: Yes, daddy.
Sanj: How much do I pay?
Arya: Three Ows
I guess that’s the currency in Arya’s world because I heard her using this word for money a few times.
Sanj: I’ve got 5 here in money. Give me 2 back in change.
Arya: Goodbye Daddy.
Sanj: I’m giving you 5 and I need 2 money back from you.
Arya sorting out the items on her stall: Bye Daddy
