Complainers

Recently, someone mentioned that we complain too much, ungrateful as well. I could understand why he felt so, there are negative bunch among us, those who complain non stop. Well, i can't blame them, that is just their nature like mine of a sarcastic bitch. But don't get me wrong i'm not supporting complainers nor condemning them for their right in proclaiming their emotions and saying aloud their penny worth of opinions.
Complain in my dictionary consist of two meaning or type, a) something you can do about it
b) there's no god damn thing you can do about it.
I'll complain and joke about my grouse about matters in the first category once or twice or maybe when i feel like it (like an introductory information you feel like you need to share with a new comer?). In second category, my upbringing had disallowed me to complain more than twice about these. Why? I know even if you complained and yell and scream and even cry about those it will not change! So why bother exhausting your energy and killing others with your negative energy? You can't do anything about your lecturers, your compulsory subjects and even your assignments, so quit it!
But those who complain non stop about category A is even as annoying as those in category B, if you have a choice to choose or a choice to change then seize it! If you hate those thing then do something about it for goodness sake instead of complaining to any poor soul who willing to listen.
But then again, i won't be the one who snap at those complainers until one fine day he or she get on my nerve then may god save he/she from my wrath( well, although i looked like a scary bitch but i have rather huge storage of patience inside me and i can take nonsense quite well).
