why?

OK,so I did a mistake on Friday and went harsh on my words.I apologise for that but why it is that some people still could not get over it?I mean,I don't really am blaming them but why it is that whenever we are scolded,we would blame the other fella but not ourselves?I dont really want to post this but there is just an attitude out there we need to change,including myself.I guess I need to resolve this problem myself..after all,the bible stated we are supposed to try 70 x 7 times.Sorry to everyone I have offended through my words.
