There is a special atmosphere in that privileged zone between the end of the day and the beginning of the night, light is over, but not completely, shadows are darker and softer as the curtain of a theatre when the show starts.
Dusk is the stage where night rehearses, before playing its magic until the following morning all over the streets.
We walk at random, there is not any need to choose a direction, the centre of Bruxelles is small and the streets are like a ball of threads which lead always to the same point, sooner or later.
