Certainly don't feel ANY child should feel "grateful" for the love and care of their parents. As an adoptee, I look at all the sad situations many children are forced to deal with and it's a matter of "Thank God I didn't have to live like that". Unlike children that are raised by their biological parents, I know that without adoption, my situation could have been negative instead of positive. Children raised by their biological parents don't feel the "could have been different" feelings.
Hope those that feel adoption is the result of an evil industry will read the following thread "This is my story as an Afather"
This is my story as an AFather
Evil industry? Procurers of children? Certainly not in this case!
