I get good grades and invitations from Scholars Academy,my mga kaibigan say I'm really smart and cool, so I don't see why you are asking such a question? And you have no right to say such a thing about people since people called smart aren't always exceling at every subject, smart just is another word for good at, nowadays. Either way, this tanong is clearly a not well thought out question.
I think a better tanong for us to ponder is: 'Where did all the stupid people come from?'
(If the stupid people all came from somewhere, and are now here, then it logically follows that the smart people left to go somewhere, probably where all of the stupid people came from. Since they are here, the smart people probably decided to go where all the stupid people are not, where all the stupid people left from. Lol.)
Or maybe, just maybe, they were swallowed sa pamamagitan ng aliens...
We are all smart...it's just a choice of we all wish to embrace it or not...or to even use it our intelligence.^^ Please don't go saying that there are no smart people around...cause I see them everyday...And they are my friends, and everyone who is answering this question.
