Personally, I would not ponder on it for too long. Even if you told him directly that you felt offended by the way he talked to you, he could only apologize and probably tell you he wasn't trying to be mean, but its unlikely that he will make you change your opinion about him, or that he will prove to you that there was no reason to feel offended. Just try to keep your conversations as few as possible and give him a genuine reaction when he says something that offends you again. Just communicate how what he says makes you feel, even stop him for a moment and tell him how he was being rude. — stimulate 10 secs ago
