Rude people in the world

I need a place to vent. So I guess this is the place. ERRRRR. I wonder why there are some people in the world who think that they are the be all to end all. Don't they realize that they just make themselves out to be a jerk. And that no one will eventually want to be around them.
How does one deal with this person? Let them rule the world and make your life uncomfortable? Or just go on an ignore this person? I'll have to think on this for awhile.
