The Brother, The sister < and The pest

so here is the deal, im the oldest of 7 and as of now im the only one with devices. my issue is not with them watching/playing with them, but they think "he is sleeping so imma use his use his stuff" this is not a big deal (although annoying) but when they start to argue about my stuff annoys me off for 3 reasons. 1(they will be throwing my pc and 3ds around trying to keep it from eachother. 2(i cant find my chargers fpr awhile. and 3( this really makes me mad.....THEY COME AND WAKE ME UP TO MAKE ME TELL WHO EVER IS CAUSING THE PROBLEM TO STOP. every time that happens i take my <censored> and sleep on it. Try getting it now punks t(-_-t)
