I don't mean to pry, but 2 questions:
1. when I gave those same qualifications at my disability appeal about the kind of job I could work (non-judgmental), I think that's when they made their decision - no such job
2. re behavior at home chores etc - didn't that show up on the questionnaires about how he functions? does he need another review? I forget, was he kicked out of group housing, is that why he is with you? it would be nice if the voc rehab worker would treat you not as family, but more like a group home, where he had expectations he had to fulfill.
