Be it, however, neither of the aforementioned, attempt, through study, to divine the true nature of this discontent of the spirits. Be it one-sided, or two? perceived or actual? based on a single slight or on the personality as a whole? be it a fault of pride or morals? be it miscommunication or deliberate misconstruence?
Once you have deciphered the source of this discordance, the challenge then lies in both overcoming any causitive fault which in you might lie, or in overcoming--if at all possible--the reasons this animosity has grown and thus the animosity itself.
It need not be necessary to alter the essence of the underlying relationship into one of friendship, nor familial ties, nor of love; however, a final product much akin to civil and public respect, such as that between business partners or that of many-ties removed acquaintances.

Ponder what in yourself could be the cause of the other's dislike or malcontent. What about your words, your actions, your countenance; what about your expressions and replies, about your affectations and mannerisms might be displeasing or unsettling to the existence of the other?
