Why does a colleague occasionally chat with you, but sometimes he doesn't want to say hello to you when he feels it, explaining what is embarrassing? What should I do?

Everyone will encounter all kinds of things every day, and your colleagues should be a little introverted and a little inferior. Not good at communicating with people. It's boring to meet something that you are not good at expressing.

You can take the initiative to chat or take him to a food stall to play games.

Seek adoption and praise. thank you
