Moved out just shy of 25 and it took about a month to realise that all the years of what i perceived to be nagging about cleanliness and tidyness was, in actual fact, just plain old common sense and their desire to not be living in a pig-sty.
It was tough moving out mainly because in the beginning we spent most months being absolutely brassic, tho the bills were always paid. Even now it kills me spending money on stuff like washing powder, bog roll and toilet cleaner when there are far more important things to buy like pc components and beer!
When the time is right, you'll go for it and enjoy it when you do!
