I'm 20 and havent lived at home since I was 18. I don't have my room anymore, but the thing is i'm always doing something at school so at most i'm living at "home" for a week to two at most.
When I graduate I will probably try to live at home for a year to gather cash and then move out. I love my parents, but I want to get to the point where I can help THEm, rather than always me...not that I could help my parents too much since my dad is a Professional Engineer, but it would be nice to do something like foot my little brother's college tuition (tuitiation...not dorm whichis 10000x more expensive 😛)
