Not long ago, I was driving down a long, flat stretch of highway and listening on my iPod to an interview of Billy Collins, former poet laureate of the United States, he of such soul-ripping lines as, “You will always be the bread and the knife, not to mention the crystal goblet and — somehow — the wine.” In the interview, he kept saying things I wanted to remember, bits and pieces of sentences that I wanted to scratch out on tiny slips of paper and stuff into a phylactery and feel bouncing on my forehead as I walked through the day; phrases I wanted to tattoo on the underside of my eyelids so that I might fall asleep staring into their mystery and contemplating their magic; single words I wanted to turn into Tropical Fruit Life Savers and dissolve on my tongue in all their artificially colored sweetness. I’ve been trying to cut down on writing while I drive, though, so instead of reaching for the pen and pad I keep in the console, I opened this relatively new app on my phone.
