i watched when it first started and all i could think about was my dad, i stayed with my gran and growing up she was visited by someone i called uncle, i never new my dad was not my dad until i was 11 and asked my gran if she was not my dads mum or my mums mum then how was she my gran, something we doing in school about family trees, she told me my uncle was my dad, met him at my grans funeral then called him when i had my son, he wanted to just leave things the way they were, 6 years ago i started to think about him, i wanted to find him and hoped it would not be too late, i put a notice on facebook missing people and my half sister who is ages with my son saw and said to her half brother, he emailed and gave me a phone number, i called and it turned out he had been looking for me but did not know my married name, we met and the first meeting did not go well, he refused to talk about the past, i said i was fine with that but...i said i felt sorry for him, he has been on his own for 20 years and he has been the one who missed out on a brilliant daughter and has an amazing grandson and a beautiful great grandson that he will never get to know. we are good friends now and we talk every week, but he will never really be dad, i think it will be the same for a lot of the people on long lost family, most of them grew up with a mum and dad and finding biological parents is great but they will never be mum or dad, i think when you are an adult you find that too much time has past and they can't just slot in to the role as a parent, they will become good friends and more like an aunt and uncle.
