On Sunday we celebrated my youngest daughter’s graduation from high school and documented the occasion with scads of photographs. My favorite one is of all of my children. I look at their three faces and wonder where my babies have gone. Sometimes my arms ache for their warm little bodies and the soft weight of their drowsy heads resting on my shoulder. The next moment I’m fascinated (and sometimes frightened) by watching them navigate the world as young adults, making choices independently and choosing their own direction. And then sometimes I see flashes or hints of where they might be heading— a new maturity or a deepening interest. How intriguing it is that I miss who they were, while appreciating who they are, and anticipate who they are becoming.
