How to establish a good concept of friendship

Friendship is a kind of special emotion produced by people in communication activities, which is essentially different from general goodwill produced in communication activities. Friendship is an emotion from a two-way (or interactive) relationship, that is, the condensation of feelings between the two sides, and any unilateral good can not be called friendship. Intimacy is the core component of friendship, and intimacy is also known as an important indicator to measure the degree of friendship. Rogers (1985) summed up this intimate relationship from three aspects: (1) being able to reveal his thoughts, feelings and inner secrets to friends; (2) Fully trust friends and be sure that their "confessions" will be respected by friends and will not be easily leaked or used against themselves.
