There are two people I know, who I consider to be very good friends. In fact, I consider them brothers. But most of all, I consider myself unbelievably privileged to know them. Talking to them is a depressing thing, not because they are depressing people, but because they are hideously intelligent. You think you've got to grasps with a skill or subject, then you talk to them about it and find that actually, in comparison to them, you know next to nothing about it. They are my Stephen Fry's, they are my David Mitchell's. If I want confirmation on anything, I don't look in a book, online, or ask a teacher - I go to them. And not because I keep them on any kind of pedestal but because I have yet to hear them say something which isn't right.
