Dude, are you saying you didn't mean what you said? You said to ask you anything. You did not say, ask me anything as long as it isn't something that you consider private. Anyway, you kind of gave a partial answer by responding that you don't know if you have any regrets.
I did bad things, maybe even horrible things, evil things, in my life, but idk if I regret it, it was part of my growing up, you know?
