“My treat!” Nice words to hear, huh? They have flowed into my ears from any number of places. At Thirty-One Flavors on a smoggy, stifling, sweltering August afternoon after I’ve ordered a double-decker “pralines ‘n’ cream, dark cone” with a buddy. He digs deeper, faster. I start licking, smilin’. Full of gratitude, I leave wondering why I ordered two scoops. We laugh. I say thanks.
