Friends end up alone, living in tents in suburban backyards, applying liberal amounts of deoderant from the back seat of white cars.
Friends get sick, turn into skeletons, leave the world.
Friends get on airplanes and fly away. Wonder if they will come back one day. Sure enough, there is darkness in this world but there is also light, somewhere, hiding like a virus. Coax it outside. You sit in your house, sweating, watching blinking lights on the stereo.
