The lights are on but nobody is at home definition and
Lights shine on a dwelling, but when it comes to no one, they stay unperceived. Dwellings void of individual presence stay dull. Not a soul to acknowledge the illumination, absence of people's residence to enlighten. Abandoned properties remain desolate of illumination, leaving the lamps meaningless. Lamp searches occupants, but in no one's property, there's absence of people to brighten.
