"Steve Barker [or possibly Chris Barton, or something along those lines]. I was in your brother's year at school. How can you not remember me? You're a famous memory man, I've seen you on TV!"
See, the non-famous-memory-men-and-women of the world have me at a real disadvantage now. They know all about me from my many TV appearances, whereas I, with my famous inability to remember names and faces, know nothing about them. And yet it's me who ends up looking stupid! I tells ya, it's tough being a celebrity.
Anyway, I don't remember any Chris/Steve/something-similar Barker/Barton/something-like-that being friends with my brother. I didn't pay much attention to those little urchins in his year, but I knew all his closest friends, I thought. I should be at least vaguely aware of the existence of someone who, when told that our grandma lives in Chilwell like he does now, observes 'oh, is she still around? I remember Joe used to go to Chilwell to see her on his holidays...'
Perhaps he's some kind of conman. Or perhaps I'm just really, really bad at remembering names and faces.
