There's a certain time of the evening; long enough after sunset for the twinkle of street lights and and transmission towers; not yet late enough for the first stars to appear.
A time when silhouettes are backed by the fading blue hues of the day tinged with green, orange and grey.
Welcome to the twilight zone.
