My parents kicked me out at 18 so they could allow my sister's boyfriend to move in with them. It's been 5 years since then and they have suddenly reached out asking for help for my sister because her boyfriend left her and they are struggling. I just laughed in their face told them why my sister had him move in and now they are speechless.
