Because they love to laugh, some male colleagues will deliberately play jokes on others, thus causing dissatisfaction. How can I stop such a thing?

Do you mean yourself or someone else? But I think it's the kind of person who likes to laugh. It may not be a joke that makes people laugh for no reason, so it is normal to attract male colleagues. I can tell you that even if I don't like this person who loves to laugh, I will like to tease her very much, because she is cheerful and everyone can't help but make her laugh. This is normal. Of course, I mean the women here. If you're talking about a man, I think that's almost what you mean, because it's not necessarily the attraction of the opposite sex, but it's probably because his low laughter makes you can't help teasing him. As for how to stop it, it is cold face, saying nothing, and even adding something funny, cold face, in fact, I don't think it is necessary. If what you say can really make the teased person laugh, then why not smile and everyone will like to get in touch with him.

If you are obviously unhappy and can't help laughing, then my advice can only be clear. Next time I'm tired of making such jokes. Make it clear to others, either with a cold face or with a temper. It's that simple.
