I have cerebral palsy.. My voice embarrasses people, I have taken speach classes as a child and my voice is where it is for the rest of my life. +my cerebral palsyed walk embarrasses people. My shaking hands embarrasses people. in fact a DHS caseworker tried to claim I was seriously mentally disturbed because during a meeting with her I was under stress which agrivates the control I have at keeping my arms and hands from spasming and jerking. I have takes rehab but again I am at the maximum function level that I can be. sometimes the things I do and say things that are are different from others because Cerebral palsy is a neuromuscular desease in which brain cells have died.Rehab and classes can only do so much in teaching the good cells to take over the work of the dead brain cells.. There is nothing I can do about this or allieviating other peoples embarrassment. They either have to accept me the way I am or it's good bye your loss.

You said the staff knows he is like this and are not doing anything about it so that tells me there is most likely something on file like a medical report explaining that these things are beyond his control. I know you are not going to like this but these behaviors may be "ABSOLUTELY unacceptable for you but for him he may be medically at his best and now it could be a matter of you accepting him or not. Telling him he is an embarrassment is not going to solve the problem. In fact it may make his amount of control worse.
