It’s a funny thing to complain about, but most of America is perfectly devoid of smells. I must have noticed it before, but this last time back I felt it as an impairment. For weeks after we arrived I kept rubbing my eyes, thinking I was losing my sight or maybe my hearing. But it was the sense of smell that was gone. Even in the grocery store, surrounded in one aisle by more kinds of food than will ever be known in a Congolese lifetime, there was nothing on the air but a vague, disinfected emptiness. I mentioned this to Anatole, who’d long since taken note of it, of course. “The air is just blank in America,” I said. “You can’t ever smell what’s around you, unless you stick your nose right down into something.“Maybe that is why they don’t know about Mobutu,” he suggested.
