But not all acquaintances are friends. We come to know many people either in the way of business or by mere chance --- say, having been at the same table at a dinner party. We may be on nodding or hand-shaking terms, call each other “friend”, sometimes write to each other with the salutation of “Dear So-and-So”, etc., etc. All these are, in fact, nothing but civilities of social life, as hypocritical as the polite formula dunshou (kowtow) or baibai (a hundred greetings) used after the signature in old-fashioned Chinese letter-writing.
We may call them social intercourse, but they seem to have very little in common with genuine friendship. Real friendship between two persons originates perhaps from the time of life when they were children playing innocently together. Real friendship is easily formed in primary or middle school days when, being socially inexperienced and free from the burden of life, you give little thought to personal gains or losses, and make friends entirely as a result of similar tastes and interests or congenial disposition. It is sort of “friendship for friendship’s sake” and is relatively pure in nature.
