Moving out isn't just something you do once you reach a certain age. You need money and the only way to get money is to find a job and then you need a job with high enough salery to afford your rent, food and whatnot and to get a job like this you need not only have good grades but also a lot of working experience and almost always a driver's license. At least that's how it works in Sweden. So moving out is easier said than done. But really, adopt meeeeh! :p
