megalomaniac: If you describe someone as a megalomaniac, you are criticizing them because they enjoy being powerful.
Guess what. I have two of them. One at school and one at home. The one at home is my oldest sister. Because my parents are in the USA, she automatically assumes the place of authority. I mean, normally shes annoying enough, but now she has so much authority, she bosses us around like nobodys business. I'm serious. Its UNBELIEVABLY ANNOYING!!!
The other one at school is my CLASS CHAIRMAN. SO ANNOYING!!! He wanted to put my name in the class conduct file for SMILING. ITS SMILING FOR GOODNESS SAKES!!! Humph. I'm pissed. Im gonna go play some games to vent my anger. bye bye.
