Ahem....in the class there is one extra person, one asshole and one siao kia. The asshole likes to provoke the siao kia, and the extra person likes to be extra, and both piss the siao kia off. The siao kia has no choice but to express that he is pissed off. But then insensitive people still say stuff about him, which makes him more angry. So lay off the comments and let the siao kia be. I know you gain enjoyment and entertainment but, spare a thought for others so others may spare a thought for you.
