Do you and your significant other always sleep on the same sides of any bed?

I'm with Jeff on this.

I guess it happened on our honeymoon in 1992, but at some point, Terry and I settled on which sides of the bed we would occupy for the rest of eternity.

From the point of view of someone standing at the foot of the bed (creepily staring at us as we sleep), you will always, always, always see me on the left side and Terry on the right.

Was there a reason for this? Or did it just kind of happen?

I don't know. You could argue it should be the other way around, since this arrangement puts our non-dominant hands nearest our respective night stands (Terry's left, my right). Not that it's a problem to roll over a little so we can use our preferred hands to grab our phones or whatever, but I can't remember if there was a reason we settled into our permanent sides of the bed.

NOTE: This is assuming we're both on our backs. I start on my stomach and end up on my back, so I guess it's not a problem at the beginning of the night and turns into one by the time I wake up.

Interestingly, when I travel for work and find myself alone in, say, a king-size bed, I sleep way over on my normal side. The other side remains untouched, as if I'm expecting Terry to show up in the middle night and just slip in beside me.

Most of us are intractable creatures of habit, to the point that it's uncomfortable for us to do certain things in our lives any other way.

I could sleep on what I consider to be Terry's side of the bed, but it would feel weird.

I could also vary the order in which I wash myself when showering, but again, weird.

Granted, to keep your brain sharp as you get older, it's a good thing to vary routines and challenge yourself every day. But I guarantee I will be sleeping on the same side of the bed and making my breakfast the same way until the day I'm 6 feet under.

Some things may not be worth changing.
