I stayed at home for two years after high school; and I've now been living on my own for less than two months now. I went to my local community college, but transferred somewhere away from home and I now live on campus. I might move back in with my mother when I finish my BA and start law school, mainly due to financial reasons.
I don't plan on living with my parents forever, and I'll be on my own for the next two years anyway 9 months out of the year. I plan on getting my own real place after I finish law school and am admitted into the State Bar, but given the state of the economy, nothing's guaranteed.
