Pissed Off

Arrgg.. can anyone tell me why are some people sooooo mean?! I just asked something from 'someone' (I chose not to mention a name) through YM because I know that that-someone is online. I've waited for the reply, but that-someone suddenly go offline. I mean, what's the meaning of this. I didn't do anything to deserve such action to that-someone. As far as I remember that-someone made an offense against me and that I should have the right not to treat that-someone nicely. Well, I'm damn good if you may asked. I know how to forgive right away. But why do some people take it against you even you don't do anything wrong. You know, that-someone can just answer what I was asking and that-someone can go right away. I'm not asking to have a long chat! Sigh. What a cruel world! I felt really bad!
