RE: UNRAVELING MY IDENTITY

Yeah, I think I'd do same. There's really nothing to be mad about if they treated you well.

For some other people, I think the best way to handle such a situation is for both parties to be as transparent as possible to the child involved

I'm not sure there's a need to be transparent about issues of adoption unless the need arises. First, there's the fact that it'll be difficult for parents to have a conversation of that sort with you, especially children in this case. They're not mature enough to be able to understand and process information like this anyways. If transparency ever comes into play, it should likely be after the child is grown enough to be able to understand that just because they're telling him/her that they're adopted does not mean the family loves them any less or that they're trying to rub in their face.
