Me: Megan, get in the bathroom and brush your teeth already.
Megan: I need you to brush them for me.
Me: Uh, no. Go brush your teeth, NOW.
Megan: I can't do it myself.
Me: Yes you can. If I can pick up all of YOUR stuff, YOU can certainly brush YOUR teeth.
Megan: I can't.
Me: Give me one good reason why you can't brush your own teeth.
Megan: Because I'm crawling.
