Dude you are paying for that hour!! I would have told my t, "uh do you need to go floss?" And even offered to give him some privacy if he didnt leave the office, or stop it.
This reminds me of my previous t. We did not do well together. I think he was trying to toughen me up. I did not need toughening up. I told him, but i dont think he got the message. I told my current t - i have had enough. I need a safe place. I need cuddles. I need what i never got. I need someone to care, not to poke. A toothpick is definitely a poke.
If a toothpick does not bother you, then it wouldnt matter If your t used a toothpick. But if a toothpick DOES bother you, then if your t uses a toothpick, it does more harm than good. That is hanksters theorem for mona.
