I could use a little of this ...

but since it's not the beach I'll be walking tomorrow, I will find happiness instead on the University of Pennsylvania campus, where my students and I will be talking about Joan Didion's essay, "On Keeping a Notebook," and taking a stroll with our cameras.  Maybe one or the other of us will catch the sun.  Maybe we'll fall in love with a detail.  Maybe something we see will bring us back to ourselves.  It's all worth hoping for.
