What better reminder do we have than our kids of our own best selves, our less stressed and more carefree selves? In their silliness we see the echo of the way we used to be: when we were kids, yes, but also before we had kids, or even two weeks ago, before all of the stress of these year-end corporate meetings. Their joy, their infectious enthusiasm, their sense of "mission" as the poor dog is dressed in boxer shorts, cannot help but cajole you, and beckon you, to lighten up.
