The lights are on but nobody is at home definition and Glow brighten a home, but when it comes to no one, they stand unseen. Residencies lacking people presence remain dull. Absence of people to greet the illumination, no one's home to brighten. Abandoned properties remain desolate of illumination, leaving the beams meaningless. Illumination seeks occupants, but in absence of people's residence, there's not
a soul to brighten.
