In High School I wrote a short story called “Day and Night”. Basically cities were so over populated that people lived and worked in shifts. Everyone had to share houses and jobs, so the day people went to work, came home, and at the end of their shift were locked into their rooms, and then the night people lived in the house and went to work, etc. There was like a 4hr overlap where they might meet each other and it had a horrible story about forbidden love been a “dayer” and “nighter”.
Anyway, house sharing in shifts. Just saying…
