Loneliness and alienation are partly due to personality and partly due to experience.

Some people, naturally introverted, are not good at dealing with people, have few friends, and spend most of their time alone.

Some people, originally cheerful, can quickly get acquainted with everyone and have many friends, but after some things, they look down on many relationships and start making friends selectively, becoming more and more arrogant.

Ji Bolun said: "Loneliness is a sad companion and a close friend of spiritual activities."

In other words, lonely people are often sentimental, rich in thoughts and delicate in feelings, and it is difficult for ordinary people to enter their inner world.

People who like to use black and white headshots express their personality and heart through the loneliness shown by the back itself.
