Yup. Once Thrag and Gok decided being in the same cave meant one could gather fire wood while the other hunted something to cook on that fire privacy went away. There was a time in history when we moved to stone buildings that were frequently single family dwellings it looked like we were increasing privacy. Unless your wife was in the sewing circle or garden club, then you knew that was an illusion. Through most of history only the very rich have had privacy... unless you count the butlers.
