People who thinks they are right

If there's one type of person that annoys me the most, it's the type of person who always thinks they are right. No matter what the situation is, what the winning losing rate is, these people always finds excuses to make their statements correct.

I think there's a word for these type of people.... dick-holes right? LOL! Ignorant perhaps? But whatever it is, yeah... it really ticks me off <___<'''....

Like for example today, my work colleague asked me a question about something that he doesn't understand, so I explained to him a few methods on how he can tackle it, but he keeps insisting that all my methods doesn't work, and that the error is something fatal or somakumlaoshit like that. When he says that my methods doesn't work, you can tell that he's thinking "Oh shit, how come I never thought of that... geez I'm such a dumbass, but I'm smarter than this dip shit, I gotta find an excuse to prove him wrong".

But when I proved it to him that the methods that I mentioned works, he went silent for awhile, thinking "Oh shit, he proved it to me.... can't make myself look like a fool, I'm better than this dickhole" and he changes the topic to another error that doesn't exist at all in the problem <__<''....

There are times where you HAVE to lose.
"What goes up WILL come down"
"To fail is to succeed"
And like Michael Jordan said "Maybe it was my fault that you didn't see that failure gave me strength".

So please, don't be a dickhole. If you know you're wrong, put down your weapons and be spared.
