Today I found a pair of Park Tools needle nose pliers I lost many years ago. I waited and waited for them to turn up and, when they didn't, bought another pair a year or so ago. I had become convinced that they had grown legs and walked away. I had good reason, at the time, for this belief, but that has now passed. I can't even say where it was I found them; they just turned up in the secret place I always put them, to prevent them growing legs. I can assure you they weren't there a year ago. Or last week. It's all very odd.
