I'm a gwajyo indeed n' I pretend to know the things. But I don't know. I had one conversation. Some1 asked me 'do you agree that you don't know anything?' I said 'yes'. He asked, 'do you agree that you know that you know nothing?' I said 'yes'. He said, 'you just said that you know nothing. Then, how come you can say that you don't know anything. If you don't know anyhing, then you can't know that you know nothing as well'. Boring talks?
