If you don't read the article, "father" implies his son was a child, but his son was 36.
Father doesn't imply that. What sort of implication is that?
Father implies that, the person who had the delusional spiral was his son, that son could be adult. The title is absolutely correct.
Biologically and relationally, he in fact remains his fathers child.
I also took no such implication from the title? It might be your interpretation, it was not mine.
