There is nothing more painful than fighting between family members. Whether is between parents who are married or divorced or between siblings, there is nothing more bitter than watching people who once loved eachother say painful things to one another. Family knows eachother better than anyone. They know each others vulnerabilities and can hurt eachother in the most private and intimate places. So before you say something to a family member, no matter how much you think that they deserve it, remember, the pain memory of this encounter will last much longer than the satisfaction of a good one liner.
