When you sleep over a friends' house,

I say that would have to depend mostly on the age of the people in question. When I was a child it was nothing to have a friend come over to my house to stay the night and share the bed. As I got older fewer friends stayed over and they all slept on the floor, I gave them my bed, or they slept on the couch. I can't even imagine sharing my bed with anyone other than my wife now.

we do sleep on same bed fi place isnt suffiecient we do other arrangements ...
