Relatives and friends greet each other with courtesy.
This is an emotional interaction between each other.
This is also a normal interaction between people
The number of times a gift is given,
does not prove the reason for suffering a loss.
Only by coming and going can the relationship be strengthened.
If you have no friends or relatives, ah.
No opportunity for courtesy, no communication!
Why do you think people live in this world?
The answer is complete, I hope you will accept it!
