Ali's Infamous Left Hand

Ali has determined that her left hand is her naughty hand. Here are some examples of conversations that we've had recently.

Scene #1 setup: Ali moving her straw up and down quickly on her McDonald's cup in order to make that really annoying noise.
Me- (worrying that she'll spend the whole 18 hr drive to CA with my parents making that noise)"Ali, please stop doing that- it really isn't good manners"
Ali- "I know- it was my left hand."

Scene #2 setup: Ali throws a little bouncy ball behind the piano
Me- "Ali! What did you do that for?"
Ali- "What?"
Me- "Now you have to wait for Dad to get home before you can play with your ball. That wasn't your best idea."
Ali- "I know. My left hand just made my right hand throw it back there."

Scene #3 setup: Ali is supposed to be brushing her teeth
Me- "Ali, have you finished brushing?"
Ali- "Almost"
Me- "What's taking so long?" (It had been about 20 minutes.)
Ali- "Mom, can you punish my left hand? It's making fun of my right hand. It's saying, "Right has an owie!"
Me- "What?"
Ali- (in a sing song voice- imagine Na- Na- NaNa- Na)"Right has an owie...Right has an owie"
Me- "How am I supposed to punish Left? Put it in time out?"
Ali- "Yes."
Me- "If Left is in time out, how will you brush your teeth?"
Ali- "I don't know."
Me- "Why don't you just focus on brushing your teeth and when you're done you can put Left in timeout yourself."
Ali- "Perfect!"

Scene #4 setup: Ali is in the backseat arguing with person/persons unknown.
Me- (after turning off the radio to be sure that what I thought I heard was actually what I heard) "Ali, who are you arguing with?"
Ali- "My left hand."
Me- "Why?"
Ali- "I don't know."
Me- " "
And the argument continued.

I'm not really sure why/how this discovery was made. It sort of gives new meaning to the phrase Choose The Right.
