I was adopted as a child then lost contact with my biological family. I was able to reconnect with my brother and sister in my early 20s via social media and whatnot. I moved out to be near them for about 5 years before coming back home. Randomly one day, someone reaches out saying they think we are siblings and they have already found another sibling before reaching out to me. I don't believe anything but after meeting and a few DNA tests later we found out we are full biological siblings. We all meet and have a reunion. About a year later, someone else reaches out to all of us and we then find another brother. We all grew up within an hour of each other and had no idea. I think about how this would have never happened before social media and its wild to me.
