Light is hope. Dark is hopelessness. We follow the light, which leads us out our despair. Dark has different shapes, but we only concentrate the blaze. However even the brightest thing has the dark side.
Seemingly our current world shiny, modern and cool; and the mementoes of the old world are vanishing in the dark. Budapest is also a fashionable and glittery city, changing as time wishes, and in the downtown only the tiny windows trying to twinkle the remains of the old-times.
