I was 25 and still living at home and still had to follow some rules, although it was things mostly out of respect for not having to pay rent. I could come and go as I pleased, but I needed to be home at a reasonable hour 12-1, not too unreasonable compared to having to pay rent and other bills. Heck, I didn't move out on my own until I had been married almost a year, although by then I was paying quite a bit on the bills and there was no mortgage so no rent. How good can you have it.
