That day, at 8:10, as every day since years, the man appeared at the metro stop. As always he carried the same briefcase under his arm and he had the same look on his face. At about 8:17 the subway train arrived and he got in, as always in the second but last wagon. Since it is one of the earliest stations of the metro line, there are always enough seats free, so we can always sit. As always, the man sat down on the bench near the door where he got in.
