Parrot, anyone?

I swear that L doesn't listen to me when I ask/tell her to do something.  EVER.  Then, she goes and proves me wrong by parroting what I said to her back at her sister!

*****
Me:  E, where are you going?  E?  E, come back here!  E, where are you?  What are you doing?
L:  Don't worry about her, just worry about yourself.

L:  Gimme that toy.
Me:  What do you say????
L:  Give me that toy, please.
E:  NO!
L:  What do you say????
E:  No, please!

*****
Me: E, take off your shoes, we're inside now.
E:  *ignores*
Me:  E, take off your shoes, please!
E:  *ignores*
L:  E, Mama said take off your shoes!  DO IT!
E:  No!
L:  Take off your shoes!
E:  NO!
L:  *wrestles E to ground, pries off shoes*
E:  NO!  NICE!  (be nice) NIIIIICE!!!!!
L:  You be nice to me, I be your mama!
Me:  No, I'm the mama, you're her big sister, and don't wrestle her like that!
L:  But I a good helper, yes?
Me:  ...
