When he arrived at a shoe shop, he felt in the pocket only to find that it was not there. So he said apologetically, 'I have left the measurement at home and don't know the size. I'll fetch it in one minute.' With these words he hurried off as fast as his legs could carry him.

He ran back home, found it and then to the shop again. But still it took him quite a while and the shop was already closed then. He had gone to all this trouble for nothing and did not get his shoes.

Then someone asked him, 'Did you buy the shoes for yourself or someone else?' 'For myself, of course.' he answered. 'Then why don't you try the shoes on by yourself?'
