I spoke rashly. How can I get rid of this problem?

Before you speak, say what you want to say to yourself three times in your mind. If you really feel the need to say it three times, then say it.

This is what Carina Lau said to Tony Leung Chiu Wai in those days, because although Tony Leung Chiu Wai is not the kind of person who talks a lot, Tony Leung Chiu Wai's words are always sharp.

What's more, if you don't have a sense of humor, don't joke in the first place. You can try joking with your best friend first and ending with a joke. If it works, you can continue to do so in the future. If not, don't use this method in the future. At the same time, you can learn from humorous friends around you and see how they joke.
