When you meet, what do you mean by asking about your family?

As soon as we met, we asked about our family.

When the two sides are unfamiliar, just ask directly. There are many situations. Maybe he has watched you for a long time and never approached you, or he doesn't have enough connotation and doesn't know what is the most important thing for a person. Or he's direct.

What you think depends on your feelings and judgment. He may be frivolous, superficial, straightforward, or just a way for him to communicate and make friends.

What kind of person he is depends on what you know after your future contacts.
