people move out for many different reasons.
some examples include , university being a fair distance away ( I had to move interstate, thus "move out" ).
some people just dont want to live at home , but personally , if i think its a better option to stay at home if possible when studying.
I quite honestly cant see a point in moving out and paying your own rent if you don't literally "have to".
having said that , alot of kids have problems with their parents etc and i cant really dispute that , but i just think alot of kids make the stupid mistake of moving out when they can save $300 a week and stay home. = save alot more money for cars , , houses.. whatever their intentions for the future may be.
