Its a hard call with a TBI its all about new coping skills and learning to work with something that does not work the way you would like it to. If the owner is frustrated take that multipy it by 100 and that is how frustrated he most likley is. If he is forgeting to charge then that is not what he should be doing. In other words the encouragment should be about what he can do. In order to rebuild confidence. It takes a long time to re train the brain with lots of set backs.
I am touched that people care as so few are shown this.
Thank you
