Why are there still people who behave badly...

i thought things have changed after so many years....i nver thought this person will never change his behaviour...and bad attitude..which i totally disagree through my whole life.! I was told that he has done something that i had never expected, what a shame! I dont have anyone to share with, so just wanna let it burst here....really...i hve been keeping this for almost a week...and i cant keep it anymore!!
I wont reveal out the person here...but he is so close very close to me since i was born i can say!!! Pls la stop what you have been doing i cant stand with the peoples talk....anywhere, everywhere i go ppl will not stop talking bout you...pity the people who live around you.....Oh God, do change this person coz this person is giving me so much pressure in my life...and sometimes ppl dont have the passion to be polite anymore when things become worst.........
