I lie about my name
Is there a reason to even lie about that?
It is a secret, I don't want to tell you.
You should be honest with people about your name. If you aren't they could call you by the wrong name.
I'm never going to tell you, maybe you should be more concerned about your own life.
I can respect that I guess but not everyone is going to be that understanding. It would just be better to be honest, especially with something as simple as your name.
