I moved out at 17 When I went into the military. After the military I lived with them for like 3 months untill I found a new place of my own. I never went back even when I was in situations where I had a very poor financial situation. I've had times where I didn't eat 1 week a month for months due to 'cashflow problems'. Learned a lot in those days
My parents wouldn't mind me staying longer I guess. Leaving home wasn't difficult for me, but it was hard for my mother to let go for a while.
