On what side of the bed do you sleep?

If you live together with your partner and you share a bed there’s about a 99.99% chance you both have your own side of the bed. Without thinking about it you get into bed at your side, and your partner gets in at theirs. How these sides are divided is a bit of a mystery, because do you remember when you ‘decided’ on what side you sleep on? Probably not, because you subconscious is the most important motivation!
