Responsible older sibling + kind of bratty younger sibling who fight a lot but actually love each other on a deeper level than most people will ever comprehend
my mom has a little brother who's only a year older than me so he and I just decided we're siblings because that's less complicated than trying to explain things to non-latinx people
lol yeah i technically have three brothers but they're so much younger they could be my children (seriously, my godson is the oldest's age) and i never lived with them so. still extreme only child vibes.
yeah Justin's actor was the buddy in Cory in the house and they were like "you can be a lead in a show" so The Amazing O'Malleys was supposed to be that show, until Disney was like "actually were launching a network for boy shows so now we want Disney shows to have girl leads"
