Today I was out walking when I became conscious of my middle two fingers tackling the little finger, yanking it so it was perpendicular to it's previous position, and holding it down. The little finger was very appreciative: Ah, that felt good!
No, I'm not just writing this to be silly. I came up with a phrase for something. It occurs to me that some of my postures that are the oddest -- and most comfortable -- are variations of "bend and lock": First bend a finger, arm, leg inward and rotate it differently than the way it grows out of its socket. And when it's rotated to wear it feels comfortable, grasp it, lay on, wedge it somewhere -- yes, somehow lock it into place... but not for long, because a lot of other things are waiting to be bent and locked, too. (Hey, the little finger had it's turn.)
The things we can look at and only think we see. You might look at me and notice that my fist was clenched, but fail to notice the reason: One clue is apparent when you look very closely and observe that the other fingers are curled around the little finger, holding it in that perpendicular position.
