I Have a Weird Sense of Humor

Its not humor but when im in a room full of people id always remain calm and literally make up a plan where id kill and takedown everyone in there, yeah im that weird lol.. Like keep smiling and answer only when someone talks to me and keep mostly to myself and to kill the boredom id make up this plan.. Damn, its does sound that bad now that ive typed it.. I seriously need help lol.. I have no life..
