“Parents should throw these slugs out of their house ...”
That’s rich. Their divorced parents should throw them out for not getting married?
I can’t speak for the person who wrote that. But my interpretation was that parents should strongly encourage their adult children to grow up and take adult responsibility for their lives. And part of that would be settling down. Hopefully that person will come back and explain what they meant.
I’m still married to my first wife, nearly 32 years. But neither of my sons is basement-dwelling slugs.
