What do you mean, just saying?

If he knows you well and is confined to the same sex, in fact, he really wants to say something to you, but he is afraid of saying something wrong, or he hides something and pretends to be indifferent to you. If he doesn't know you very well, she just talks to you tentatively to see who you are or what you think of something. If she knows you well and is confined to the opposite sex, she really wants to share something with you, but she is afraid that you are not interested and wants to share it with you. Note that if you listen to "casual talk" too much, you will gradually fall into a direct heart-to-heart communication with each other. If you want to get along with people sincerely, don't expect others to talk less, but don't create a language environment for people to talk casually.
