Ellie has great feedback for you here! For my two cents,
Quote: "can you call them back later when we get home?"
I would change this to " would you call them back later when we get home?"
Using "would" or "will" statements is Martianese and implies the choice to comply or not. You get a lot farther with Martians speaking their own language, especially when they hear you are giving them a choice! It doesn't sound like nagging!
