For the short while we were together, you had an empty box of floss on your bathroom countertop. I mentioned it to you towards the end and you hadn't noticed even that it was completely gone. Three days before we broke up, on the last night we spent together, I brought over a fresh new box. You have since returned most of my belongings, but you kept the floss. I didn't need it to be returned, but I can't help but think about it occasionally. I picture it there—a tool to keep you in good health, an opportunity to form a new positive habit, a strange last effort by me to “help you”—and I sincerely hope you use it. —From me
