I don't know you, man, and I don't know what the hell you want to do.

( maybe he just wants to ask question for the hell of it or he's trying to bother marcos or it's a combination of the two. he doesn't know and he doesn't really feel like talking about his past with someone he doesn't know either. )

Why don't you tell me what you want out of asking me these instead of playing twenty questions? Might get you what you want quicker.
