i moved out for a bit when was 20 - 22, moved back home for a few years as parents house could be divided a bit so myself or them werent in each others face all the time, had own space and we never clashed, i could still easily be there as it was cheap and very easy, but just moved out with a couple mates few months back, its great being out of home just costs a bit more, savings no way near what they used to be and have had to change spending habbits a lot.
some people thrive on moving out young, others like myself arent to phased, but i spose it depends on the house your living in with the olds.
