How to greet people

1. Call someone first

2. How are you doing recently (elderly), do you seem to have lost weight (female under the age of 10)? Have you taken good care of yourself recently? Your face looks really good (female of any age), This dress looks great (female of any age), have you traveled recently (anyone), how are your children (if you know the children) ), how are your babies (including human babies and dog babies)

3. Really? ...that's it. That's it. (After catching up on the topic, you can act as a repeater)
