What should I do if I meet a snobbish and boastful colleague?

You just ignore such people. Let him live in his own world and be narcissistic. The more you talk to this kind of person, the less he can see the level of eyebrows and eyes, and the more he thinks you are his bragging force, because he always thinks you are not as good as him, and the more he thinks you are buttering him up. He is the father you will never get. The more you talk to him, the more you encourage him to show off, so the best way to treat such people is to be silent. He always shows off to you. At first, you told him I was busy, so you just said it. Later, you can tell him, I think you are right, I am busy now. You can just say that I don't have time to listen to your lobbying in the future. After a long time, if this person is not too thick-skinned, he should know what you mean and won't cut off his own money again. If he's still the same, why don't you just say it, brother It's really bad for you I don't want to hear you brag. Listen to me, do high-profile things, keep a low profile, don't show off if you have nothing to do, it's not good to be too rich. He should understand what you said. There is no need to care about a garbage man. It is much better to please yourself than to please others.
