I heard of a guy who always had a different excuse why he was late for work, which was often. Then one day when he turned up late yet again his manager said “don’t tell, this happened.” And sure enough that was his excuse. Next time he was late his manager again told him why he was late before he said a word. On the third occasion this happened the manager again told him why he was late but then added an extra piece of information which explained how she knew.
It seems that someone had informed her that they had come across a book which listed reasons why people were late for work and that list tallied with the excuses he had given.
He stopped being late for work. He had no more excuses.
