Do boys like girls' circle of friends casually? What's the point?

There are several situations in which boys praise girls' circle of friends:

The first category is boys you have never met or are unfamiliar with, that is to say, there is no intersection in real life or business. If you are a married lady and you have exposed relevant information in your circle of friends, you can almost 100% be sure that the other person is just flirting with you and playing with you.

If you are an unmarried lady, you can also judge that the other person is flirting with you, basically playing with you.

The second category, boys who know or have business intersection in reality. Whether you are married or not, and whether you have talked about friends or not, the compliments or comments of the other party are only friendly to you and have little other meaning.

Third, your circle of friends or conversation reveals that you are single, and then, if the other person likes or comments, you should understand the other person's feelings. If you are married or have a girlfriend, then almost 100% can be sure that the other person is just teasing you. If the other person is single, it just means that he likes you, nothing else.

What I really want to express my love to you is not to praise or comment on everything in your circle of friends, but to chat with you directly on WeChat or QQ regularly, such as asking: What are you doing? Have you eaten? Or reveal your happiness or troubles in the chat sent to you. Please pay attention to the word "regular". Not occasionally. At best, it's a slap.
