stupid people in a stupid world

i hate to be 自大 (even tho i m) and i hate to say this, but 99.9% of the time i m right. but this world is just filled with even more 自大 people who likes to insist that they are right and i dunno where their confidence come from, but i hate to argue with them too. i like to let them see the result of their own stupid choices, tho i m affected too. i dun mind being affected if it can help them to learn a lesson and learn that they are not as clever as they think. but the prob is they never learn. they forget that the bad result is due to their initial stupid choices and they lose memory that they even made the stupid choice in the first place and push the blame to others. luckily or sadly my memory is better than them, but i always remember who made the stupid choices. but anyway nothing is gained from it at the end and the vicious cycle continues and i have to live my sad life while continuing to be affected by stupid choices from stupid people. nice life i have.
