I worked with a young man who told me he was adopted.
His reaction to the question about his natural parents was simple.
His parents were the ones who had brought him up. He had no interest in who had given birth to him and had given him up.
All I can suggest is to be open and honest with questions.
To stress your love for them.
I was adopted not long after I was born. When in later years I was made aware that I had been adopted my feelings were exactly like those of the young man you mentioned. As far as I was concerned my real parents were the two wonderful people who adopted me and who cared for me and loved me. I had no interest in contacting my birth parents.
I am fast approaching 75 years old and sadly both my parents are long dead, but never once in all those years have I ever had the desire to contact my birth parents.
Just last year a friend of mine told me that his 23 year old daughter had in fact been adopted and that she was actively trying to contact her birth mother. I told him that I too had been adopted but unlike his daughter had no desire to contact my birth parents.
What happened to the daughter over the next few months is a rather cautionary tale. When her birth mother discovered contact was being attempted she clearly resented this and wanted no part of it.
It was a real hammer blow to the daughter, and to her felt like a second rejection.
Fortunately, she belongs to a home where there is plenty of love and this has helped her come to terms with things.
My friend never said as much, but I had the feeling that he and his wife felt a certain amount of hurt that their daughter wanted to contact her birth parents.
In the light of that I can only imagine that had I tried to contact my birth parents that it might have been hurtful to my parents as well.
