I walked through the grocery store with a secret. I put the individual cups of mac-and-cheese that I found so repulsive, but that my kids clamored for, in my cart. Still, inside I was smiling. I swung my cart past the boxes and boxes of Technicolor cereal, pulled a cartoon-emblazoned brand off the shelf, and nonetheless gloated. I loaded snack-sized metalized polypropelyne bags of air-riddled, cheese-flavored corn puffs on my pile–and my heart soared anyway. Because I knew something no one else around me knew.
