Pixar\u2019s latest flick holds some major life lessons for kids \u2014 and adults, too. Inside Out takes place inside the head of an 11-year-old girl, Riley, as she and her parents move from Minnesota to San Francisco. The main characters are cute personifications of the main characters inside of each of us: Joy, Sadness, Anger, Disgust, and Fear. Joy, played by Amy Poehler, runs the show, attempting to keep Sadness from bringing Riley down as she struggles with her family\u2019s move. As far as Joy\u2019s concerned, Sadness is a downer. And really, what\u2019s the point of being sad anyway? Riley\u2019s parents pile on by encouraging her to be happy all the time and praising her when she manages a smile. You might recognize this parental behavior, because it\u2019s a common one. At one point or another, parenting means finding yourself in a situation when your child\u2019s emotions are really, really inconvenient. Sometimes in a public place, frequently over an issue that \u2014 to you, as an adult \u2014 is no big deal, and often with loud sobs and crocodile tears. What do you do? Some parents try to dismiss their child\u2019s emotions. Others use anger: \u201cStop crying or I\u2019ll give you something to cry about!\u201d I\u2019ve even heard an adult try to scare a kid by telling her that if she didn\u2019t cut it out, nobody would want to play with her. Adults do it to one another, too. Most recently \u2014 and most egregiously \u2014 I was told to \u201cthink positive\u201d when a friend was killed by a drunk driver. \u201cWe all go eventually,\u201d a would-be counselor suggested. \u201cAt least for him it was fast.\u201d No, I\u2019m sorry. I need to feel sad when I\u2019m sad. We all do \u2014 and that\u2019s the lesson of this movie. The plot shifts from Sadness-as-a-bummer to Sadness-as-a-hero when another character loses a beloved toy. Joy tries her antics to cheer him up, but they don\u2019t work. Then Sadness sits next to him and empathizes. She listens to him, really feels his pain. The result? He cheers up. It\u2019s only by truly feeling your sadness that you can come back to joy. That\u2019s true of anger and fear, too. Yet many of us are conditioned to repress our painful emotions in an attempt to make them go away. Only they don\u2019t. And it\u2019s really unhealthy. This isn\u2019t even news. Over 25 years ago, The New York Times reported that people who repress their emotions are more prone to asthma, high blood pressure, and \u201coverall ill health.\u201d More recent studies have found links between suppressing anger and migraines. A Huffington Post writer puts it plainly: \u201cKeeping your emotions bottled up could kill you.\u201d Every parent wants what\u2019s best for their kids. But our attempts to get little ones to stop crying might have long-term consequences for their mental and physical health. It can be uncomfortable to feel a child\u2019s pain, to truly empathize with him or her. But Pixar gave us a gift with this movie\u2019s moral: We need all our emotions to be healthy \u2014 including the ones that hurt.
