I would say that it depends on the circumstances.
I lived with my parents until I was 20, then moved out when I got my own apartment. I was still in community college and worked full time. I eventually stopped going to community college.
After a few years on my own, I decided to go back to college... but for a bachelors degree instead. I applied for RIT, got accepted... then moved back in with my parents. My lease ended and there was no point in renewing it since I was going to go to RIT in a few months.
I just graduated last year and moved back here with my parents. I have school loans to pay off. My dad is a traveling businessman. So, I'm staying here to help my mom out while I'm paying off my loans. When I get a very good paying job, then I will move out and get my own apartment again.
There are some people who stay with their parents their whole life... that's bad. There are some people who graduate from college and then move back in with their parents without even doing anything... that's bad.
I know someone who spent 8 years getting his AOS degree. After graduating, he lived off campus with roommates for a year... then moved back home with his mom. He refuses to get a job. (The only job he had was 2 days at McDonalds.) His mom pays for everything. He gets weekly allowances, which he always spends on beer (and weed). :roll: Now, that's sad.
