You could just pee the bed and blame the dog...........win win.
Not if you keep telling my secrets, it's not.
When I was growing up, I was specifically told by parents that the man sleeps closest to the door, so if anyone breaks in at night he can fight off intruders. I was also told that no one would ever marry me because I couldn't open a car door by myself, so I've wondered if the 'rents were accurate (as I eventually married anyway, but to someone who also felt he needed to be by the door). Quite exciting to find this thread to find out how people sleep, as I've long been curious. Over the years I've asked people, " So what side of the bed do you prefer?" , but I found that question is often misinterpreted as an invitation.
I switch. I will sleep on the right. I will sleep on the left. I will sleep in the middle. I have 6 cats, and three dogs, and I just want sleep. Sometimes I move from my bed to the couch. They follow me. I have a three legged cat, and he courteously moves to the night table and waits for me to get up, and come back. The rest are heat seeking barbarians, and I'm lucky to end up with room to rest. My dogs are Chihuahuas, and they like to be under the blankets, thus they aren't visible. I don't want to squish anyone, but they are stubborn, and they get comfortable and I have to be very careful to get back in bed without injuring them, or myself. Last night I had to go to the top of the bed, climb over a cat, and carefully insert myself under the covers in the middle of the bed. Another dog and cat was on the right side, and a dog on the left, with two more cats...
The worst thing is if, for some reason they decide to sleep with Madri-Guy or the cats sleep outside, I can't sleep At All. I miss them.
At one time, I took a good look at this situation, and realized that because of this situation, I would always be sleeping 'alone'.
This means I'm not technically qualified to answer the OP's question, but it might explain why.
