Thank you everyone who gave me some very helpful replies. I am sorry I didn't respond but I was waiting for this week's session where I planned to say it to her. I was practising how to bring it up like cynefrids suggestion and I was just going to bring it up when she took out her diary and from it she took out a toothpick... she continued to direct the remnants of her lunch for what seemed like a very long time. I was very distracted and disgusted. I would consider that bad manners but t continued. I was so shocked I couldn't speak. Now sometimes t pulls so unusual stunts even for a t but this was the worst. She asked me if I was angry because I was sitting there so quiet and I nodded my head. She asked what was happening with me and where did I feel it but I just sat there in shock. Now t has ate an apple noisily and slurped coffee but this was the worst.
