When you're young, all you want is to be older, respected, in charge of yourself. When you become an adult, you realize you've made a terrible mistake! You don't want to be in charge! Who would want that?! All the responsibility, being in charge means making decisions, dealing with the results and reactions from those choices. It's all very... serious. So it becomes, then, a full circle journey back to seeking youth, letting go of the seriousness of life and realizing that in the end most of the things you thought mattered, didn't, and the little things like a tree swing in the fall make you young no matter your age.
