People...

So the world is full of people which I'm sure everyone has noticed.  I don't really have anything against it per se but sometimes I wonder.  Why is it that people feel the need to dominate over others.  Do they really think that they know better?  Maybe it's just a certain type of personality that feels the need to have "power" so they exert said "power" over the ones that think they should have "power" over.  I have no problem with people who have earned the power and have proven themselves worthy but the ones who give the "power" to themselves and who really have no idea what they are doing...  I have a problem then, especially when I feel that I know better.  I'm learning patience because of these people but sometimes I really feel like knocking them down a peg or two.  It's just so annoying.
