One of my classmates talked many comments on his students'personarity today to one of his students. I laughed in my beard when listening to him.
I think it's nearly impossible to understand one another. Understanding one himself is difficult, let alone another. So I never have any comments on another's personarity. In fact, though I have my own view about someone, I don't think I really have standstood one another.
And that boy which is my classmate's student said he was so tired that he wanted to get off from his position. But there are too many people who are more tired than you...
IQ is different between people.
