I can't imagine doing this living with my folks. We used to live quite a ways away and whenever we'd visit for a few weeks, all bets were off. Now we live close again, and visiting there even for a few hours is usually huge temptation. Plus they really love baked goods and always ask me to bake stuff at their house. At least the cake is there and I don't take it home, but how often do you bake something and not have any? Annoying, but I am learning to manage.
