People always talk about how great it is to get older. All I saw were more rules and more adults telling me what I could and couldn't do, in the name of what's " good for me." Yeah, well, asparagus is good for me, but it still makes me want to throw up.
Many people claim that aging is wonderful, but the author in this quote sees it differently. They feel that growing older simply brings more restrictions and adult rules that limit their freedom and choices.
The quote humorously compares these rules to healthy foods like asparagus, which are good for you but still unappealing. It highlights the author's frustration with the perceived loss of independence and the unwanted advice that comes with growing up.
