lol this is a humorous question for a barefoot forum. I love the pub!
Well normally I sleep from around 8pm-2am and my husband sleeps from around 3am to noon. So we don't actually overlap all that much, but he is of the sleep on your own side mentality so we are pretty separate. I don't think that is so much an age or time together thing as a personal preference issue. The more amusing stuff is when we are hanging out with friends. Sometimes drinking is involved and no one wants to drive home and risk an accident, or another couple who I just hang out with a lot and there is no reason to drive home just to come back the next day. We've slept 4 of us in a queen sized bed and just threw us girls in the middle. Or if I don't feel like driving home from my one's friend place me him and his wife just rotate around so no one is stuck in the middle all the time.
Ramez are you actually poly? I couldn't quite tell with the last section if the whole thing was meant to be a joke or just that part.
