For months, maybe even years, I have been perplexed by a callus that unassumingly sits on the right side of my left forefinger. There’s a slightly less pronounced callus in the same spot on my middle finger. But I could not begin to grasp where this callus came from.
Suddenly yesterday I caught myself biting my finger. What?! THAT’S REALLY WEIRD. Apparently when I’m thinking while in a sitting position I will casually bring my left hand to my face and rest my teeth against the right side of my forefinger, and more rarely my middle finger.
I acknowledge that this is completely bizarre. Perhaps now that I have spotted the habit, I can defeat it.
