A few years ago, after I returned home to Seattle from a trip to Los Angeles, I unpacked my bag and found a dead cockroach, shrouded by a dirty sock, in a corner. Shit, I thought. We’re being invaded. So I threw the clothes, books, shoes, and toiletries back into the suitcase, carried it out to the driveway, and dumped the contents onto the pavement, ready to stomp on any other cockroach stowaways. But there was only the one cockroach, dead and stiff. As he lay on the pavement, I leaned closer to him. His legs were curled under his body. His head was tilted at a sad angle. Sad? Yes, sad. For who is lonelier than the cockroach without his tribe?
