the lights are on but nobody's home TheFreeDictionarycom
Beams brighten a dwelling, but when it comes to absence of people, they stand unacknowledged. Residencies lacking individual presence stay unlit. No one to welcome the illumination, no one's home to enlighten. Empty houses stay desolate of illumination, leaving the beams meaningless. Illumination searches individuals, but in nobody's dwelling, there's nobody to illuminate.
