I want to know what kind of psychology it is for a person to spy on your life, such as space, when he clearly doesn't like you and hates you. (same sex)

The world is big, and there is no wonder. There are many boring people. ...

That's what people do. They like studying other people's things very much. Even if they don't like this person very much, they can't help but pay attention. This is human nature. If you are not particularly close, your mind just likes to watch her jokes to satisfy your inner boredom ~ ~ but it is not a big problem. Just know how to grasp it yourself, and you can't get involved in other people's world.

You should be yourself at best and ignore these unimportant people directly. Because you hate someone, it is more effective to ignore him than to be tit for tat. More importantly, don't let other people's behavior affect your mood!
