Considering that I have lived with my parents and my friends, I would have to say my Parents. I know that it sounds weird. When I was living with my Parental Unit, I didn't have to worry about someone forgetting to, not having the money to, or just not help paying the bills. The annoying factor is a bit of a pain, but I would rather deal with the annoying parents than deal with friends that think they can walk all over you.
