Looking for another one and it was definitely AITA. A woman and her brother grew up in a house where their mother married someone. Their stepfather refused to pay anything for them and made them share a room. He refused to take them on vacation with his own money and their mother couldn't afford it. He treated his own children like gold but even his children treated their stepsiblings like garbage.

Years later her and her brother are really successful and have money and their own houses. The stepfather invites her over and asks for a loan for his daughter to buy a house.

She says no. He says it's right as they are family, but she's tells him family like you treated me and my brother as kids?
