Brian’s always been a bit slow.  Oh, I don’t mean in the brain department, he always scored well above average in those online IQ tests. But you ask him to nip to the corner shop for a loaf and a lottery ticket on a Saturday afternoon and they’d have announced the winning numbers before you saw him again. I mean, it’s less than 500 yards door-to-door; the kids had a tortoise that walked faster than Brian, and she was seventy when she escaped.
