Do all climbers do the thing?
Where you pull open a door with a solitary ring finger.
Pick up a mug between your thumb and pinkie, take a sip, put it down, pick it up with your thumb and ring finger, take a sip, put it down, pick it up again with your thumb and index etc, etc,
Stand in doorways gripping the top of the frame and clenching distractedly rocking on tip toes whilst conversing with people.
Carry like 8 bags of groceries with a single finger and absent-mindedly flex your grip.
It’s not that you think about doing it before hand, you just kinda do it?
