They Share One Room

Well..I experienced that when we were young..I remember we only stay in 1 room all together..No bed, No sofas only 1 small wall folding table for eating..Good thing, we transferred to a much bigger apartment when I turned 10yrs. old.

I think that such living situation in the 21st century could be only awful and terrific.

We are really spoiled in this "modern age." It hasn't been uncommon to live like that for all of history until just the last century or so. It's not good according to our standards, but who is to say what is really good for the kids and the adults? They just might interact more as a family than those who have separate rooms to huddle in.

If they are comfortable ,then everything goes well

Not an ideal arrangement, but sometimes we can only do the best we can given a situation. If the kids are older, maybe they should turn other parts of the house as a small room for more privacy. Sometimes people sleep on a couch in the living room.
