Brothers are male siblings who share at least one biological or legal parent. They can be born into the same family or may be adopted. Brothers often grow up together, sharing experiences, responsibilities, and sometimes conflicts. Their relationships can vary widely, from close companionship to rivalry. In many cultures, brothers play significant roles in family dynamics. They may support each other during challenges and celebrate achievements together. The bond between brothers can be influenced by factors such as age difference, personality, and family environment, shaping their interactions throughout life.
