Umm my parents had this idea. It seems that me and my siblings internalized the idea that our parents didn't like/care about us and ended up with quite low self esteem. Most of us developed some anxiety disorders or depressive issues. Now my 24 year old brother sits in my parents house and plays DotA all day and my parents just complain about how he needs to get a job.

e: this is after massive academic self sabotage that ended up with him barely graduating from high school on the special ed track despite being probably 130+iq. He would show up late to every class, refuse to do his assignments, and roll his eyes and loudly yawn to mock the teachers the teachers before falling asleep at his desk. Despite this he'd still end up topping out exams in physics, chemistry, etc. But there were other issues at play like my mother being sick our whole childhood and my father having emotional and social problems from an abusive childhood.
