A "brother" is a male sibling, someone who shares at least one parent with you. Brothers can be biological, meaning they are born into the same family, or they can be adopted, meaning they join the family through legal means. They often grow up together, sharing experiences, playing games, and sometimes even getting into friendly arguments. Having a brother can create a special bond that lasts a lifetime. Brothers often support each other through challenges, celebrate achievements, and create lasting memories. Whether it's sharing secrets or going on adventures, a brother can be a lifelong friend and confidant, much like a sister or family member.
