【明報專訊】Natalie is a little girl with a big problem. She was milking her cow when the cow overturned (翻倒) her pail. "I am in misery," Natalie wailed (哀泣). "In fact, I am close to tears!" The cow was much more relaxed about the situation. "A loss is a loss," the cow spoke, "and there is nothing to be gained by crying over spilt milk." Actually, the cow is right and this saying informs us that it is pointless to get upset or feel regret about a loss or a mistake that cannot be corrected or undone.
