It's not like my parents could have stopped me from eating at McDonalds with anymore seriousness than my doctor does.

Any time I'd want to eat at McDonalds after school I could ride my bike to McDonalds. I had money from mowing lawns and my mother wouldn't have known. In fact, I remember plenty of times my friends showing up and saying, "We're going to the gym" and instead we'd drive to get fast food- and then I'd come home to a dinner my mother made and she'd be like- you must be hungry after the gym! oof.

I stand by my statement that I could and did eat more fast food as a kid than as an adult and my parents hold no more sway over my fast food consumption than my doctors do. I could just as easily have lied to them as I could lie to my doctor...
