Go Silent?

i'm a talkative, sarcastic and cynical person.my words are always provocative.and things get worse because right now i'm staying with sisters...well,personally, i'm the kind of person who believe in something that we deserve...for example, if you work hard, you deserve success but if you are not, then you deserve failure..thats how it is, at least for me...so, in my interpersonal relationship, i will respect those who deserve the respect and i mean business...if you are older than me but you just dont act as how you should as the elders so thats it...i wont treat you as the way you expect me to..ok,i'm arrogant but its not my fault..if i dont respect somebody, its hard for me to treat that person kindly, well, at least, with words...ok,just because i'm younger and the youngest, i cant tell you if you do wrong, is that it?that system sucks...yes, we are malays but its just not practical to stay put when you see something wrong right?well, if that person who does wrong is your grandfather who is just counting the days, maybe you can let him slip out.thats another thing.maybe the thing that i went wrong is that i talk imprudently...thats my way of speaking and i just dont know how to reshape that attitude of mine...well, maybe now its time to go silent...just stay silent and dont talk even a word except when i'm asked to...i guess thats applicable...hmm...life's so demanding and tiring...nothing is simple...
