When I was a kid I slept with my younger sister. So what? We liked it. Plus, when the nieces and nephews came over, we slept with them, too. We had beds but for some reason they liked sleeping with us. Sometimes, we had so many people sleeping over, we slept on quilts on the floor. What an adventure! I still sleep on the floor if my back is hurting. Never killed anyone that I know of. It was a different era way back then.
Those quilts on the floor were called pallets....and I have slept on many of them.
