Nervously I quickened my pace. Dogs don't like me. It is a simple law of the universe, like gravity. I am not exaggerating when I say that I have never passed a dog that didn't act as if it thought I was about to take its Alpo. Dogs that have not moved from the sofa in years will, at the sniff of me passing outside, rise in fury and hurl themselves at shut windows. I have seen tiny dogs, no bigger than a fluffy slipper, jerk little old ladies off their feet and drag them over open ground in a quest to get at my blood and sinew. Every dog on the face of the earth wants me dead.
