I NEVER would have chosen to live at home during college! I was so eager to live on my own, make new friends, and experience campus life. It was well worth a bit of discomfort (no A/C, having to share a room, etc.) just for the freedom of not living with parents.
I would have considered it a total failure to have to move back home after I graduated; I almost didn't take a great apartment after I graduated, because it woud be two weeks before I could move into it (I think I graduated on May 15 and the apartment was available June 1) and I'd have to live at home during that time! Kids are different these days, I guess.
