  3. Sir, you're the ocean of positively and hope for me, I trust you blindly and I have faith on your teaching. Just ignore all those immature neanderthals who raise a question on your teaching. I apologize for using such words but I really get angry when someone out of nowhere doubts on you. Love you sir.
