It's a Bird, It's a Plane, It's... Super Listener!

This was a recent conversation between Marty and Emma:

Marty: You think I am super-cool, don't you?
Emma: (Joking with a big grin) Nope!
Marty: (Mock offense) What?!?
Emma: Nope, not cool!
Marty: Only cool dads let their little girls drive down the driveway. I guess if I am not cool, you can't drive anymore...
Emma: (Still grinning) Now you are just mean!
Marty: Do you really think I'm mean?
Emma: (Suddenly serious) Not to the kids, but you are mean to Mommy.
Marty: When am I mean to Mommy?
Emma: When Mommy says 'I don't want to have this conversation right now."

Why can't she listen this well when we tell her to clean her room?

FYI: I do say that when we need to discuss things away from the kids, not when Marty is being mean. When he is mean, I just whack him with a fry pan ask him politely to stop.
