Me: Hi, Zoe, what are you doing? Are you eating lunch?
She: *pause* *nod*
Me: What are you eating? A tortilla?
She: *silence*
He: Zoe, when someone asks you a question, you should answer. You could say, Yes, I am eating a tortilla, or No, I am not eating a tortilla. But you ARE eating a tortilla, so you should say Yes.
She: Poop.
*hilarity ensues*
