Dare To Piss Me Off ?

One day at home i was busy doing my sivik project until my brother came buy and start disturbing him. At first i ignore him untill he keep on throwing bits of paper to me.I get out from the chair and head towards him and look at him with such an evil stare and i told him in an angry and evil voice ' Go ahead, piss me off ! I dare u!'(with a evil smile). Then he kept quiet and went to his room and shut himself inside. Then i went back and continue doing the project.
