I feel he is tortured..(I have seen it in another)..He does need help. Even if he is the son of a famous(in this country) couple..He is still their son and they love him. I think they have done what they thought was right..It is hard for parents to live with a child of any age with this behaviour..I hope he gets some proper help. It is a long hard road back to normality for some.
Regardless of Bert's fame, I don't think life is all he would like it to be, and especially now he is not a young man himself. Funny how life can turn around and bite you on the bum...
