Have you read the book, The Snowball. It is a kind of official biograph of Warren Buffett.
I haven't read the book before! What is it about?
It's about the famous investor, Warren Buffett. You know he pretty much made himself one of the richest people in the world. 
Wow that's interesting. Was he the CEO of Berkshire Hathaway?
Yes, you are right. It's amazing how long he has been on that position.
Yeah, is it true he put 40% of his partnership's capital away into American Express?
I am not sure about that. But he did invest a lot in American Express, at least at some point. But I doubt he would put 40% into one single company.
Ahh that is interesting. What is your favorite part Warren Buffett in the book?
What I like Warren Buffett the most is that he obviously the genius in investing, but he also has great wisdom about life and how to use wealth. 
That is wonderful. Are you interested in fair trade investing?
What do you mean by "fair trade investing?" I may know the content, but I am not familiar with that name.
