David, why are you wearing a suit, man? You don’t breathe, remember? So, why wear a suit?

Holloway notices the “salt” in David’s attitude and replies “they are making you guys pretty close”. And David answers with just MORE salt: “not too close I hope”.
Why should a robot answer to a human this way? David was meant to make spectators question his amount of “robot characteristics” since Prometheus.
The answer we have now is that David was pretty emotional and “free” since Prometheus.
He faked smiles without worrying about how fake they looked. He sometimes just decided to not smile at all, like in this dialogue.
Fassbender has always depicted him as very proud. So proud he doesn’t even care, deep inside, to accomplish his duties: making people comfortable.
He really doesn’t care much about his “programs”. How is that possible?? Because he’s pretty free, since the very beginning.
