It would be as if I once went to visit my Uncle Bill in New York City when I was 7. After meeting him and getting to know his farm, I came home with my parents. Years later, my parents told me that Uncle Bill was not our real Uncle. Who did I meet, then?
This needs to be answered? You met a guy named Bill. You were told he was your uncle, and you didn't question it. But in reality, things were not as you were told.
What's so complicated about that?
