Then she pushes you away. Hard. What just happened? Well, like a swimmer who gets her breath back, your daughter wants to return to the water, and she gets there by pushing off the side of the pool. This often takes the form of picking the dumbest fight ever or being nasty in a way that is both petty and painful (“Please tell me you didn’t actually wear those shoes with that skirt today”). While you could have hummed Paul Simon all day long, your daughter needs to hurry back to the depths as soon as she feels restored. Why can’t she linger? Because, to her, lingering feels babyish, which is just about the last thing that any normal teenager who is parting with childhood wants to feel.
