Exactly. It’s what families do.
What is wrong with sharing a house? Their refusal to go back to that makes no sense to me. If I was a believer of polygamy and sister wife world I’d want to be under the same roof.
Id retreat to my room when needed but I’d at least want to reap the rewards of having my “sisters” help me cook, clean,, parent. I’d be like “oh hell yes it’s Tuesday, I’ve just got salad duty tonight” (or whatever system was determined). What’s the point of living autonomously if your end game was polygamy? It’s not economical and it’s not how families live.
