Life in Balance and Credit

My parents have friends who adopted a boy 7 years ago. James and Lillian (my parents’ friends) decided to conceal the adoption. They spent more than a year abroad and then came back with a child. Most of their acquaintances were sure that David is James and Lillian’s son and only close people knew the truth. Of course, James and Lillian want their boy would never know that he is an adopted child. But it turns out that the neighbors got to know the truth. Now Lillian and James are afraid that someone would tell their boy that he is adopted.
Well, adoption is a HARD task. It is not easy to be parents, but to be stepparents is much harder. I am not speaking about the problems of brining-up children, about misunderstanding and so on. But what’s right, to tell your adopted children about the fact of adoption, or to conceal the truth? How to make the right decision? Is the truth is always better than white lie? I have no answer to this question. The only thing I am sure about is nobody has the right to tell adopted children the truth except their stepparents.
