I'm not going to tell close friends of mine my real name
Why wouldn't you tell them your real name?
I want to keep my identity a secret.
Even from your closest friends? It seems like you would want to tell your friends everything about you.
Nah, all my friends know this and they don't care. I'm gn0r0 and I don't care.
I just think it's a little silly to hide your real name. I don't see any harm in telling them.
