Maybe I'll have to join you in bizarre then. I have two kleenex from his office that I've been carrying around in my hoodie pocket for about a year now. Not used, I promise! When I'm feeling stressed, it helps to know they're in my pocket and if I need to I can put my hand in my pocket to touch them. I also have kept every parking receipt for the last 22 months, since I started seeing him, except for public holidays when I don't have to pay for street parking. That started because I didn't want my husband to know I was in therapy at first and would stick them in a pocket in my backpack. Later I didn't want him to know where the office was located and it just turned into a thing. I showed him the stack of them one day and I think he was amused in a good way. He suggested writing what we talked about on the back of each one, but they're really too small to do that, maybe only a little over an inch square piece of paper.
