Let me join this "just a thought stuff". :) This morning, I had an argument with a guy in my group. He is a post-doc. and works with me. He told me to do something and i did it. But he changed his mind and want that work to be done in other way. That is why i argued with him. Anyway, after that argument, i came to the conclusion that everyone wants to have power over other people. So, everyone want in his mind to be a politician though it may be covered with other things. Basically, man is like an animal group and wanna have a control over others. With my short English, it is hard to describe but you guys know many examples of animal species who live together. Human being may be a little bit brighter than other creatures of God, so they wanna segregate themselves from others. but it is just from arrogance of mankind... I think you would get my point with this. I am not even sure whether this is really my point of view or not. Anyway, what do you think? :) exausted mono
