Limit break

• In Final Fantasy 6 and above(For those who doesn't know, it is a pc/console game), whenever the character controlled by the player get hurt, the limit meter will start to fill up. When the limit meter is completely filled, the character will have the ability to use 'Limit Break', an ability to do huge damage to his/her enemies. The limit break defers from character to character, but needless to say, it causes a great deal of pain to the hapless monsters that gets in the way of the character.
  
• In certain arcade games, like Street Fighter and King of Fighters, there is a 'anger meter', which will automatically charge up whenever the character receives damage. When the meter gets fully charged, the character will be able to perform special abilities which does much more damage than usual.

No, 'limit meter' and 'anger meter' are not purely fictional. Everyone has their limits. Even the nicest person will snap when his/her limit is reached. And when that happens, people will do things that they normally won't do or can't do. Push someone too far, or drive someone to a corner, and you should expect them to lash out in a manner beyond your imagination.

I am a good person. Everyone who knows me will agree to that. I have a good temper, and I am a cheerful person. It is unfortunate that there are some people in this world who loves to test other's limit. And who better to become their 'test subject' than people like me? You make fun at me, fine, I'm cool with that. You insult me, I shrug it off. You pick on me again, don't push it. Try it again, and you'll live to regret it. Just ask a former classmate of mine, who has a scar to show for pushing his luck too far.

Whenever we read in the newspapers of cases with people committing suicide, running amok, and the likes, we always see the shocked response of so-and-so's family members and friends: 'So-and-so is a quiet and good mannered person. I am shocked that he would do such a thing'. As I've said, someone who is quiet and nice doesn't mean he has no limit to bullshits that he can take. Everyone has a limit. And when that limit is reached, even the lightest straw can break a camel's back.

p/s: No, I am not thinking of committing suicide or go about kicking the crap out of the next person I see. This is just something that comes to my mind out of a sudden, so, chill.
