"How was your day?" It's a question many of us hear often, from spouses or parents or friends. We hear it so often that it's become background noise, the elevator music of our lives. But the question is profound and deserves deep reflection: What, if anything, makes a day good? Reb George Costanza famously issued his own precise recipe: A good day, he taught us, involves some combination of reading a book from beginning to end (in that order), learning to play Frisbee-golf (otherwise known as frolf), and biting into a big hunk of cheese as if it were an apple. These are all very pleasurable things (well, maybe not the frolf), but surely, there must be more.
