There are certain people in this world who tried to be funny, or pretend to be funny in order to hide their self-centered giant ego from being obviously exposed. I know of such a person who was once a developer in my team but now a contractor in a government office who happens to be working in the same building as I work at.
I found him irritating ever since the last time we met at a reunion gathering dinner. He consistently talked with the tone of I-am-above-you or I-am-managing-you kind of attitude. Maybe he got such an attitude from spent too much time managing outside vendor, and got used to using such an attitude to boss around in order to get his work done. That doesn't mean, though, he has right to use the same bad ass attitude to deal with other people, including those who are supposed to be his friend.
Imagine meeting an old friend, and his first word is " what kind of sickness do you have these days." That's the attitude of this person. I met him a few times at the building lobby, and the only word he could came out of his butt was "Hey, how can you are still around here. When could you leave here?" And then he farted again with words like "do you have nothing to do at work?"
It's kind of sad to see someone I know turned into such a inconsiderate person. But then, I don't know what kind of abuse he suffered from his boss (more of his consumer of his service as he's just a independent contractor there, thank goddness) .
