Fake persona ? I'm a regular at HN and use my real name here. Hardly a fake persona. You seem to be taking a rather emotional standpoint here for no valid reason.
I know you are a real person (duh!), but somehow I'm having doubts about the rest of it. Maybe I'm just being extra sceptical, but it would really help if you can prove your dad is really what you say he is.
If you know anything about how things work in India, you won't ask him to give concrete proof about dad. For the safety of his dad and other family members, he is right to keep details secret.
For rather obvious reasons he's not likely to want to provide proof. Please stop asking for it.
