"[Ten years ago (presumably in 2013), his son began studies at the University of Sheffield] I didn't see him for months, he came back different. He had long hair, he had a beard. His clothes were different, a different attitude and outlook on life. I thought – "my goodness, Harry, what's happened to you." He sat down with me on the settee, he put his arm on my hand and he says: "Dad, I've been away for a few months now and I've come back and I'm not the Harry that went away all those months ago. I'm different now, I'm a different person.""
