My FI was adopted. It was a closed adoption and for the first 3 months of his life he was in foster care until he was matched with his loving family.
Everyone knew he was adopted. Except my FI. No one (not even his cousins) said anything to him.
At 5 his parents told him he was ''Chosen'', but from a heavily religious family Chosen was the same term used to describe the Virgin Mary, as she was ''Chosen'' to give birth to Jesus. At 5, he never made the connection.
It wasn't until my FI was 13 (and hitting puberty if that isn't enough of a change at once) when someone casually mentioned that he was adopted. Between the new found information and many changes he was going thru with puberty; he became a cold, distant child believing that much of his life was a lie. His parents did what good little Christian parents were supposed to do, and sent him to various other people to fix him and pray over him when all he needed was a talk. FI's relationship with his ''adoptive'' family is still going thru rather rough patches (nearly 17 years later).
I know that this is a single case, but my FI needed to hear the story of how a wonderful woman gave birth to a baby boy but wanted a better life for him and put him up for adoption, as opposed to just being told he was ''Chosen'' as a child.
There isn't really a moral to this tale, I just don't want other families torn apart over a simple misunderstanding.
