In the corner of the room there were postcards of highway scenes; dark expanses of asphalt under stars and moons, but no sun. Every once in a while, in one of the postcards, there would be a street light to give the impression that the roads were in use.
All the postcards were blank, except for one that said "see you at the party!". There was no address on it, just a little drawing of a sunflower where the sender information should have been.
When I left the room, I stacked up all the postcards and left the one with writing on it to the side for the next person to find more easily.
