Women's facial expressions can tell fortune.

How to analyze the meaning of a woman's smiling expression?

I think it should be considered in combination with the sending scenario.

1, she is very happy.

She may be trying to tease you and show that she is very happy, and deliberately use the smile expression that the old man thinks to attract your reply and attention.

She is teasing you, feeling that you are old now and don't know the irony of smiling face. I'll explain after you ask.

Look at the age, or she really doesn't understand. Maybe she really thought it was just a friendly smile.

Second, she is unhappy.

She is in a bad mood and doesn't want to talk to you. She gives you a smile.

She doesn't want to talk to you, she wants to end the conversation with you, but you can't see that she has been chatting. Out of politeness, she replied to the customer service with a smile.

She thinks you are annoying, mocking you silently and expressing her dissatisfaction with you.
