My husband's cousin adopted two girls. About five years ago, we became suspicious that the girls didn't know that they were adopted. One had medical issues and wanted her mother to take a genetic test. She couldn't understand why her mother wouldn't do it. My husband and his cousins got together and told her the truth. The fall out has been interesting. The girls have found their bio mothers and the adoptive parents swore to never speak to us again. I'm good with that.
