Everyone, without a doubt, has little things that are unique only to them. Sometimes they share them with others to varying degrees. Personally, when I make sandwiches, everything has to meet the edge of the bread, I don’t care what it is. It’s allowed to hang over, of course, but the crust must be met. I also wash my dishes very carefully, whereas my husband has left a lake in the vicinity when he’s done. My quirk amuses him and his quirk bothers me. Not enough to get divorced over, though.
Then there’s the perpetual, “which way should the toilet paper hang, over or under” issue. It is, oddly enough, some of these smaller things that feel like they’re almost part of our character.
Some can be repulsed by outie belly buttons and others are turned on by them, and it’s a darned good thing because not everyone has an outie belly button and if there wasn’t someone in the world who didn’t like innie belly buttons I’d be up the creek.
Have you noticed that I’m rambling, and that’s one of my own little character flaws, some love it and some want to just smack me because of it.
