The so-called "friends" are very important contacts in interpersonal relationships. A friend refers to a person whose interpersonal relationship has developed to be irrelevant but very friendly. True friends are usually honest, loyal and loyal to each other, and the first thing that comes to mind is each other. Their interests may be similar, and they may often get together. If you are "good friends", don't talk about interests; If we talk about interests, we mean interests, not friends. Immortals also have no way to "control" and talk about interests between so-called "friends". In short, as good friends, there is only selfless help and dedication. Otherwise, it is a conflict of interest.
