if your parents lived in a huge house & you didnt have to see them ever if you didnt want to whats the point in getting your own house?

this is what i feel like at the moment, not that ive never lived on my own before, i just spent 4 years in a different country but now that im back im in no rush to find a new place to live infact i think i might just spend a few more years here tbh... i mean my sister and her husband lived here until she was 31.. and im only 28
