I accompanied a Uni girlfriend to go shopping last night. She was running errands for her busy husband and buying stuff for him. Out of the blue, she turned and told me she remembered one time when I was running errands for my first ex too. She said she remembered me searching for dental floss for him, and that I got agitated when it couldn't be found. But I can't remember any of it. I was criminally ruthless about forgetting him about we broke up. I am aware of my notoriously bad memory, and had systematically removed every trace of him... contact details, birthdate, photos. And after all this time, nothing has remained. In the end, she offered me an old memory which I've completely erased.
