Me: Hey, could you take my phone and answer Daddy's text message? Just type "yes" and hit the OK button.
My Daughter: Okay.
Me: You can send Daddy a text message of your own if you want.
Her: Really? Okay! *Pause*
Her: Mom, where's the apostrophe?
Me: I don't remember off the top of my head. Don't worry about it.
Her: But Mom! *Exasperated sigh* The word "it's" has an apostrophe! It's a CONTRACTION.
