I lived at home until I was 24 I think, around about that age anyway. Only moved out because my Mum moved up to Lincolnshire and I wasn't invited!
Lived with an ex girlfriends sisters family for a couple of years then managed to get the place I am in now.... In a way I am glad my Mum sort of kicked me out as I would never have got a place of my own in this day and age.
