She did try to do the physical part (and to be honest, my hands are not that bad, you see far worse in YouTube videos!) and I believe we got there. The problem is that I have an anatomical difference in the way my thumb bends (it bends back naturally without any strain or effort) and she has an idee fixe that it is the root of all my problems. She is partially right - it is the root of all the problems between her and me (joking!).
