1. There is no distance between confidants.
I think everyone has had this experience. If two friends haven't met for a long time, they will feel unfamiliar when they meet again. This is due to the common failure to meet and communicate. During this period, they have different experiences.
but this kind of situation will not happen between confidants. A hedge between keeps friendship green. No matter how long it takes, seeing or not seeing each other, when they meet again, they will have the feeling of returning to that time for a moment, as if the last time they parted was yesterday. Because although we don't see each other, we have always kept each other in our hearts.
2. There is no interest entanglement between confidants
In life, we will make friends with all kinds of people for various reasons, mostly because we have various needs. Those who want to study will make friends with those who have studied well, and those who are looking for a job will go back to make friends with those who have work experience. Of course, there will be cases where they become friends because of similar interests. But neither can escape the word demand.
Only friends who have no interest needs can become bosom friends, and they don't need to get anything from each other, so they don't need to please or calculate, and some just cherish each other.
