15．When Joan gave birth to the first boy in her family in three generations，she and her husband were overjoyed．So were her parents．Joan expected her elder sister，Sally，to be just as delighted as them．Joan had always admired Sally---the beauty and the star of the family---and felt happy about her achievements．But since the baby's arrival，the sisters have become distant．Joan feels hurt for Sally seems completely uninterested in her baby．Sally，who has no children，claims that her younger sister"acts as if no one ever had a baby before．"
Neither Sally nor Joan understands that the real cause of the current coldness is that their family roles have suddenly changed to the opposite．Finally Joan seems to be better than her elder sister---and Sally doesn't like it!Their distance may be temporary，but it shows that childhood competition don't fade easily as ages grow．It can remain powerful in relationships throughout life．
In a study of the University of Cincinnati，65 men and women between ages 25and 93 were asked how they felt about their brothers and sisters．Nearly 75 percent admitted having hidden competitive feelings．In a few cases，these emotions were so strong as to have affected their entire lives．
Many adult brothers and sisters are close，supportive---yet still tend to compete．Two brothers I know turn into killers when on opposite sides of a tennis net．Off the court，they are the best of friends．My own younger sister can't wait to tell me when I've put on weight．However，she's a terrible cook and that pleases me； I tease her when she comes to dinner．Happily，despite these small failings，we have been an important resource for each other．
In between the very competitive and the generally supportive children lie those who say that no friendship should survive． Some brothers and sisters stay at arm's length，but never give up competition completely．Why do these puzzling，unproductive，often painful relationships continue to exist？
