Someone sent a message. Hello.

When the other party sends a message, hello, you return it politely. Hello, this is normal reciprocity. If the other party sends you a message, wouldn't it be rude if it were a friend? The other person will think that you look down on him, but since you think that you are strangers and have nothing to say, then ignore him and stare. If the other person is testing you and wants to lay hands on you, that's not good. Anyway, don't disclose money, personal information and family, so as not to hurt yourself and your family.
