As a parent and guardian of an adult child with special needs I think your parents need to piss off . If your sister is doing better you have every right to do and keep on what you ' ve been doing . It ' s so awesome you ' ve taken this role in your sister ' s life . They ' ve been trying to contact her ? If they haven ' t been in regular contact all along they have no right to call themselves parents . If they ' ve been really this much out of contact , start putting together a timeline and any other documentation you might have if it gets bad , you may have to try for a restraining order . <| sep |> We do it all the time ? <| sep |> I think the evidence is the opportunity . Remember that if anything DID happen , they would meticulously avoid leaving evidence . Opportunity and motive might be all you get .
