So, Ellie and I are in the grocery store. She is sitting in the back of the cart reading her book while I push her along filling the cart. We go around the corner and I hear this loud, kind of a honking sound but think nothing of it until Ellie says in her outside voice (naturally) "I tooooooted."
I very casually say "Oh. And what do we say when we toot?"
She says "Excuuuuuse me!"
Acting if nothing happened, I keep pushing the cart and walking away with several giggles coming from behind us.
