I know you don't think anything of it. I know for you, a pen is just a cheap utilitarian tool, and that a Paper Mate Write Bros. is not anything to be obsessive about. Hey, I've got seemingly dozens of them scattered about my house (literally dozens in unopened bags, but all sorts of individual pens in different locations in the house where I can easily access them), so an unknowing observer might think they mean nothing to me. And when you come to the front table and have forgotten to put your name on your assignment, and you see a pen (my pen) sitting there, I'm sure it's just instinct that makes you grab for it.
But I have one simple request.
DO NOT EVER TOUCH MY PENS.
