why can't people just shut up and stop making trouble?

hais... I wonder why some people can't just zip their mouth and just mind their own bussiness? I hate these type of people. I just don't understand why can't they just mind their own bussiness, I don't touch you, you don't touch me, I don't talk, you don't talk! you can talk but it must be nessecary! but I wonder why can't people stop commanding another person. The main question is why can't they mind their own bussiness? I know everybody likes to command people but when people command you, what is your reaction? Maybe, your reaction will be "you have no right to command me" and the other person will say "you also commanded me!" and you will say "no." of course, most people will refuse to admit that you commanded that particular person. My sister just came in to the room and said something unessecary she said "get your f*cking file off!" but what did I do? I was just sitting on the chair and put my Science journal on the table and write my concept map. but she just come in and say it! such and irritating little bitch! now she's trying to make stupid noise, she's an idiot
