Physically, I've slept at my friend's several nights in a row and it is not a restful sleep. It's hot as hell in there, and he has three perfect, beautiful (feline) daughters that I love but they all sleep on top of me, so it's 4 cats total, and that generates A LOT more heat. Not to mention all the kneading, all the little needle toe kneading. The mattress is filled with barbed wire though so it's not like the kneading is the most prominent source of pain. I can't move because I don't want to disturb the cats. So sometimes I'm just like god, why am I so lovable? It's a prison
