It's not good when your 2-year-old drops a toy and says, 'Oh, shit.' In a very calm voice, just like a certain parent.
Also not great when your 5-year-old is having trouble working through the tangles in her hair, quietly puts the brush down, studies herself in the mirror for a moment, and says, 'Hell.' In an eerily similar tone to the above-mentioned parent.
They probably learned that from their father.
Not from their mother, who curses like a sailor.
Yeah, they definitely got that from John.
