Sarcasm

Recently, Sacarsm has been introding my life a lot.
Sacarsm is divided into three,
1)sacarsm funny
2)sacarsm hurt
3)sacarm rude

There is this person / individual who tries to be sacarstic to me, and i think he thinks it is funny, but little that he realize that his sacarsm is really hurtfull, there are times where i am patient with this kind of characters and i put up with them, but there are times when i lose my temper, I dont like to loose my temper when it comes to frenz, and at places where i have my reputation, but situation forces me to...
There is this another individual, who is pushing me up to the wall, i have yet to loose my temper with him, but the day i loose my temper with him will be the day man that he really know who i am
When someone is sacarstic, why do they try to cover it by laughing... well hahaha
what is soo funny when u pass such a rude comment which mite offend that person??
