“Recently, I observed a three-year-old boy and his five-year-old sister freely dancing with abandon to a song that had come over the radio. What struck me was the innocence of it and of them. They were dancing just because they could and just because suddenly they had felt like it. It made me reflect on my own innocence. What had become of it? When was the last time I spontaneously did something carefree and joyous merely because I felt like it?”
