Why are young brothers annoying?

siblings are annoying cuz if they're younger, they want your attention, and they think that the best way to get it is to be annoying. if they're older, then they probably just think that you're too little to understand and have fun with them. also, you live with them, am i right? and whenever you live with someone you find their faults more annoying than other people do because you have to see them ALL THE TIME. i have younger siblings so i understand.
