<For this essay, i think you'd changed my tune in essay, it became flat & emotionless, actually it's an emotional essay, after editing, I feel like I can't recognize it's my essay...>

I am sorry if my changes make you feel that way. At least it is now an essay written in proper English. Perhaps you just cannot expect a 100-year old man to have too much passion left, even if he wants to show a bit of it in what he writes, hehe. And you should first try to learn to express your ideas well and correctly first, before learning to express your emotions in a dramatic way.
