My kids will likely always consider the house they grew up in as their home. Even when they do buy their own places.
See, and the house(s) that I grew up in, my Mom hasn't lived in them in years. Same with my kids - they can go back to the house in Middletown if they want, though, see who's living there now.
If something dramatic happened - I got sick or seriously injured or my folks needed help, something like that, I *could* go live with them; but that's what I'd consider it - "living with my parents".
