Would you tell?
Many of us have not - or cannot (for many different reasons) - meet and speak with our first parents. Many adoptees have suffered abuse or neglect either during the child placement process, or after. [Meaning abuse took place at the orphanage/children's home/foster home or within the adoptive home.]
If search and reunion were in fact possible, and you were promised an opportunity to have a quiet conversation with one or both parents, would you tell them you were abused by other people? Is there a parent you would be more likely to tell? Do first-parents have a right-to-know what happened to their relinquished child?
