「家家有本難念的經」，兄弟姊妹之間可能產生不和的原因相當多。主要的問題之一是兄弟姊妹擁有迥異的性格和價值觀，這可能導致在溝通和相處上的各種困難。最常見的衝突源來自父母給予某位小孩更多的關注或資源，可能引起其他兄弟姊妹的不滿，甚至形成競爭心態。

例如父母去世後，若無法公平分配財產，最終可能使兄弟姊妹變成彼此之間最親密的陌生人。而孩子們之間的年齡差異較大時，可能處於不同的生活階段，面臨不同的壓力和挑戰，這導致彼此理解上的不足。若家庭經常爆發爭執、吵架或衝突，而難以快速解決，會讓家人之間的關係產生長期的負面影響。

此外，一些家庭的教育方式、價值觀念和家庭氛圍也可能對子女之間的相處產生影響和矛盾。例如，疼愛讀書的孩子或傳統的重男輕女觀念可能造成兄弟姊妹之間的摩擦。當家中有特別高學歷或事業有成就的孩子時，父母容易差別對待。而若長期缺乏良好的溝通，可能導致孩子們之間的不理解和疏遠。

"Every family has its own challenges." There are many reasons why siblings may not get along. One primary issue is the diverse personalities and values among siblings, leading to various difficulties in communication and interaction. Common conflicts arise when parents provide more attention or resources to one child, causing dissatisfaction or even fostering a competitive attitude among other siblings.

For instance, in the event of parents' passing, if there is no fair distribution of assets, it may eventually result in siblings becoming the closest strangers to each other. Age differences among children can also contribute to being in different life stages, facing diverse pressures and challenges, leading to insufficient understanding between them. If a family frequently experiences disputes, arguments, or conflicts that are not resolved quickly, it can have a long-term negative impact on relationships within the family.

Furthermore, various factors such as parenting styles, values, and the overall family atmosphere can influence the relationships between siblings. For example, favoritism towards a child with academic achievements or adherence to traditional gender roles may cause friction among siblings. When there's a child with exceptional academic or career success, parents may unintentionally treat them differently. Without sustained and effective communication over the long term, it can result in misunderstandings and emotional distance among the siblings.
