He said: “This front wheel wobbles.”

I said: “It doesn’t if you don’t wobble it.” It didn’t wobble, as a matter of fact—nothing worth calling a wobble.

He said: “This is dangerous; have you got a screw-hammer?”

I ought to have been firm, but I thought that perhaps he really did know something about the business. I went to the tool shed to see what I could find. When I came back he was sitting on the ground with the front wheel between his legs. He was playing with it, twiddling it round between his fingers; the remnant of the machine was lying on the gravel path beside him.

He said: “Something has happened to this front wheel of yours.”

“It looks like it, doesn’t it?” I answered. But he was the sort of man that never understands satire.

He said: “It looks to me as if the bearings were all wrong.”

I said: “Don’t you trouble about it any more; you will make yourself tired. Let us put it back and get off.”

He said: “We may as well see what is the matter with it, now it is out.” He talked as though it had dropped out by accident.
