Adult children are moving back home with mom and dad

Those "Adults" are Parasites. The parents will never get rid of them.
I emotionally detached from my parents when I was 12 because they made it clear to me that I could never expect any help from them. Things were so crazy in that house, that my older brother dropped out of school and moved in with my grandmother and sponged off of her until she died, then he moved back home to sponge off of my parents until they died.
I was working a crappy part time job only making $40.00 a week but I saved it. One night my dad came to pick me up from work and he was drunk and nearly got us killed so I decided it was time to buy a beater. I got my driver's license & went looking for a car. Did my parents offer to help me buy one??? No. But, they bought my younger brother 3 and he trashed them all.
When I finally was able to move out of that den of iniquity for good, I never went back, no matter how broke or hungry I was.
When they finally died, I felt nothing except relief. Did my parents leave me any inheritance? No. But when we finally sold their house I got enough to put a down payment on a house of my own. Then my older brother wanted to move in with me and I said NO. Families are over rated. I don't know of a single "family" that doesn't suck. Children are parasites.
