It is a bit Keith-y tho' I don't think Keith would go so far as to blame and sue his parents.
I wonder if the guy concerned has had a miserable life so far or an ongoing illness but that wouldn't be his parents' fault & the article doesn't say anything like that. How must they feel. I read what they, and he, said but that doesn't show the depth of feeling.
Depression is a horrible thing. He's only 27, his whole life ahead of him. I wouldn't say that to him of course, I'd be inviting more of the same but what I mean is, in a couple of years he could feel much better, accept life has ups and downs & like most people, make the most of the ups.
Poor soul.
