Man are greedy

That day i saw this movie on channel 5 "a beautiful mind", it is based on the true story of Nash, the guy who come up with the nash equilibrium that i'm studying in school now loh. He got a nobel prize lah, but when he came up with his theory, he was a bit lunatic one loh. Wth, we have to study a siao guy's theory loh. What does this show? That genius can be misunderstood to be crazy? Ai yah, i think the moral of the story is that even a siao guy can win nobel prize, so normal people should not lose to him and work harder.
Anyway, now i'm going to talk about a theory, similar to Nash theory lah, all MAN are greedy. If you give a person $1, he will expect you to give him more money the next time. If you knew you screwed up for a paper, so u only expect a pass, but when u got it back and u got a B, you will start thinking that you should have score bettet loh, be greedy and wan more. Like for me, i got this normal fren, not close at all, never expect anything from this fren for my birthday, but when this fren celebrate my birthday for me, i start to expect more, expect a birthday gift from this fren. Even though at the beginning, i had never expect anything loh. See, human are greedy. Another good example is that when a guy is chasing a ger, even though the ger dun like the guy at all and wun like him one, but when the guy start liking another ger or have a gf, i'm sure the ger will be super buay song lah. If u are saying no leh, i'll feel happy for him, dun come and lie lah, inside her heart, she will surely feel abit bitter one, maybe she will even say wah lao, say like me, yet go after other gers, this type of guys so hua xin. See, all Man are greedy. Just like nash equlibrium, human will choose a better choice as human are greedy. Maybe i can call this Ernest's equilibrium. Nobel Prize here i come. Hahaha, ok ok, i know is impossible, but i have my right to daydream right? Sorry about that!
