He does personal grooming sometimes.

Like pick his nails. He was jumpy last session, and was picking at one nail with the other, and putting little bits of nail in his empty water cup.

I finally admitted that it was driving me crazy when he pulled out a little nail file and started filing the jagged edges, and adding more to the cup. Which I think was pretty good because I usually don't say anything. He was proud of me too.

Once, he was rubbing at something on his shoe, then licked his finger to rub at it more effectively. I thought "Why is something too unacceptable for one's shoe acceptable for one's mouth?"

I do shudder whenever he cracks his knuckles. And he will stop doing it when I shudder.

He used to look at his phone when it vibrated. It became a huge issue to me, because I think it's unbelievably rude to pause to check to see who was calling, while we were in the middle of a discussion. It broke my train of thought and seemed disrespectful. So now it still vibrates, but he makes a special point of turning it off (if it's doing it a lot) while not looking at the screen. And saying that he's just turning it off. Or he lets me know if he needs to look at it for some special reason. Which manages to be just as disrupting, but less disrespectful I guess.

I'm sure he has a few with me. I prefer not to mop up my tears unless my nose starts to run, and he seems to be stopping himself from handing me a tissue.
