Each applicant rode up to a different floor of the visa bureau with a different kind of application and a folder with its own colored tab.
The new visa bureau opened its doors on a rainy Monday, and by nine o'clock the lift was packed. Verity, Otto, Camille and Rashid stood shoulder to shoulder, each holding a folder with a bright colored tab sticking out of the side. They all watched the little lights above the door, waiting for their own floor. No two of them had come for the same reason, and no two were heading to the same floor. By lunchtime the clerks had lost track of which folder had gone where, and only a few scribbled notes were left to help them sort it out.
