For better or for worse, I will show how I truly feel.

Today a colleague of mine commented that I really look fed up with another co-worker and it shows very obviously.  Well, I just want to say that my action is justifiable.  In my so many years of working in different companies, I have never experienced having to deal with a co-worker who is lazy, ignorant, blur, has attitude problem and has no common sense with work matters. Worse of all, despite numerous guidance and reminders, this person continues to make the same mistake and I have to frequently correct them.  Well, enough is enough!  To me, this person does not deserves any of my respect.  I would rather reserve that for somebody who is deserving, not someone who is making me "vomit blood" on a daily basis

It was shocking to me, at first, when I found out recently that I wasn't the only person in the office having problems with this person.  Seriously...what more needs to be said about such person then? 

I can have the words "fed up with...." printed on my forehead and it will still be totally justifiable.
