My family complains......?

okay this is a long story but stay with me lol. so my mom just married a new guy, so hes my step dad. and he has 7 kids and there all nerdy and is really neat. the dad is a military dude. and then my mom has 9 kids including me. my family is all about free expesion all like is arty and musical. so most of my family goes to a arts acadamy, aand its real chill like we kinda run the school and we dont have all the stupid classes like math, becasue if we get acepted in the school were garanted in the music busines or art or somthing. soo whenever we get home from school all of my step dads kids complain about how we never have homework and we get to do music stuff. how do we get them to shut up??
