A good opening line can let the other person down and quickly close the distance between each other.
There is even a type of person who will refuse to associate with you because of a bad first impression of you, and you won't even have a chance to change.
If the opening is not good, it leaves a bad impression on the other person, and you may have to spend ten times more effort to change this impression in the later days.
The first words you say when you meet someone determine the impression you make on them, and that impression is often very difficult to change.
Emotionally intelligent people attach great importance to the first sentence of the opening when interacting with others.
People with high emotional intelligence often set up a "personnel file" when interacting with people to accurately record the names and relevant information of each object of communication, so as to avoid calling the wrong person's name when meeting.
