Dad never gave up.
One would think that after so many years, he would. But he must have thought there was hope of some kind. The particulars escape me, but I remember that he always played with Michael and he always wanted to visit him at Willowbrook. When he was placed in a group home, Dad took encouragement from the speech therapist, who told us that Michael had all the physical equipment to speak. Mike never did talk.
I can count on one hand, the number of times I witnessed any kind of connection between the two of them.
