Another Puncture.

When the cry goes up, "Puncture" on a cycle run, the clever money is on it belonging to WBH. It has to be said that, even though his bible is "The Ladybird Book of Bicycle Maintenance," he doesn't mess about. He had it fixed before two other stalwarts had found the holes in his inner tube. It is important to know what caused the problem to ensure that it doesn't do so again.

My father used to say that the most important part of learning any skill was holding your tongue in the correct attitude. WBH clearly subscribes to this point of view.
