That could be a situation in which, for instance, when we interview the applicant--who is, let's say, 15 years old--we find that the child doesn't know that he or she is being adopted. When we interview the biological parents, they don't know. They know their kid is going to live with their uncle in Canada, but they don't know the details of what happened. That would be a typical case.
