Why do colleagues cling to you when they know that you have a little privacy?

Why do colleagues cling to you when they know that you have a little privacy? At work, we will meet all kinds of people, people with true feelings and people with false feelings. Why? Because the social environment is complex and people are unpredictable, colleagues should help each other and live in harmony, but some colleagues will hold you back with malicious intentions when they know about your private affairs. Why? Because your colleague has a personality problem, you should be careful of such a colleague. The correct way should be not to talk about your private affairs at work, so as not to be known by colleagues with ulterior motives, because your private affairs hold on to you. Protecting yourself is to have a good mood, and having a good mood is to work smoothly.
