The words once spoken are hard to be retrieved, just like a galloping horse that's hard to be chased. Therefore, we should think carefully and choose our words wisely before speaking, especially in important situations where our words may have a significant impact on others. Once we utter something, we cannot undo the damage it may cause, and often, the consequences are serious and long-lasting. Hence, always remember the old adage, "Think before you speak", and use your words for good.
