What is something that you don't like to share?
I don't like to share my bed.
I'm a wild sleeper. I toss and I turn and I kick and then I toss and turn some more.
Several times in my life I had to share my bed with someone. My friend who came to live with us slept in my bed with me. And a cousin slept in my bed with me when they stayed with us for a while.
I've never liked having "company" in my bed. I just lay there, wide awake, in one spot. Afraid to move or breath because I might "bother" them.
My husband even sleeps in a different room than me, for various reasons.
I make an exception for my dogs of course. They sleep at the end of my bed sometimes, but they will often get down and go away as I kick them while I'm tossing and turning.
