i am beyond pissed

why the fuck would my parents wait 5 days before school starts out of a 3 month summer to go back to school shopping, ALL THE SUPPLIES ARE GONNA BE GONE ALL THE GOOD CLOTHES ARE GONNA BE GONE, they do this bullshit every year like damn, i invited my bro to come 2 WEEKS AGO why the fuck am i just now hearing that he cant go 3 DAYS before school shopping, AND THEY KNEW MY WORK SCHEDULE FOR A WEEK, so why on Gods green earth are we scheduling to go school shopping the TWO out of the THREE days im working,
