It’s not really OCD, although I do have that “disorder.”
It’s a desire to have things be clear, for people to conceptualize things the way they really are.
My mother always wanted her daughters to be teachers, and none of us were, but I do it sometimes outside the classroom. I hope she approves.
I’m surprised that no one mentioned ending a sentence with a preposition.
What are you looking for?
