Typical TVB Plot Lines

I never understood why TVB thinks that when one realizes that one's closest had lied to him since birth, they will always go bonkers and get all pissed off and then runs away. It is usually for something along the lines of "I'm not your true father"; in my case, it is "I'm not your uncle but I'm your brother!".

I'm not going to waste time on the utter absurdities of this premise because this is TV after all. What bugs me is why would anyone suddenly feel angry in that situation? Personally I would feel shocked, a little awkward when I have to confront the person again, but angry? Hell no! I would be curious to learn about why such a ridiculous lie was manufactured in the first place. For me at least, anger is a negative feeling triggered when something pisses me off. Why would uncovering that truth negatively affect me at all? Will learning that truth suddenly change history and make my happy carefree childhood transform into a period of endless trauma and lashings?
