“Safety” is an over-heated, fifth-floor walk-up with hot-and-cold running cockroaches. They are everywhere. When I turn on the lights, the entire room moves. I often can’t face the scurrying brown multitude and leave the room in darkness. Then in a demonstration of the Darwinian principle of adaptation, the brown multitude mutates to albino making it easier for the roaches to conceal themselves on the white porcelain of our sink and tub. Their white camouflage is most effective in the bristles of our toothbrushes. The only give away is the barely detectable movement of the tiny, black, roach eyes. I want to believe that I always spot these albino interlopers before sticking my toothbrush into my mouth. I desperately want to believe that.
