He ignores you. It's also possible that he doesn't like people like you. He has a high profile. In this case, if you are the leader, then say hello. Generally speaking, the leaders who have little relationship with you will ignore the general colleagues. Everything is mutual. You say hello to him, but he doesn't reply, which makes you uncomfortable. On the surface, he deliberately doesn't say hello, but in fact, he should be ashamed of you. You are better than him in quality.
You should understand that there are many people in the world who are not good to you and they will be good to you. Maybe you were embarrassed at that time. It's a very good idea that you want to maintain a basic respect for people, but you should be careful in everything you do. Only those who deserve your respect should be respected, which is meaningful and valuable. You don't need to respect those who don't respect you, do you? This is not your fault at all, because you respect each other, so don't be depressed about such a small thing. But please respect the person who deserves your respect next time.
Some people have personality problems. For example, introverted people, when they are greeted by others, they say "oh" or "look at it" or "smile" at most. Some people don't like to communicate with strangers, some people don't like to communicate with ordinary friends too much, and some people are arrogant. When someone greets him, he will act as if he didn't see it to realize his sense of existence, He will pretend to have just heard it when others call him more, so this is not necessarily your problem, and you don't need to pay too much attention to it.
