My dad started threatening to kick me out as soon as I hit puberty. His limit was my refusal to adopt his racism and involving myself romantically with people he only referred to in derogatory terms. I had a week to pack my shit and find a place because he had already bought a new house. I was immediately disowned and battled homelessness and unemployment for the next two years. It’s been three years since we’ve spoken, he still has sentimental items of mine, and he never told me his new address though it wasn’t hard to find.
Maybe with White Americans but it’s not the case with Asian, Hispanic, and Arab Americans who let their kids stay at home until they’re ready to move out. The kids usually end up looking after their parents when they get old too instead of dumping them in a retirement home. Those cultures are just more family orientated compared to western cultures which are more about being independent.
