I've never understood people that yearn to be a kid again. When I was a kid, especially when I was in high school, I desperately wanted to get all that over with and become an adult. And when I became an adult, things were rough, but I felt so much better for so many reasons.
As I've aged, this sentiment has only been further reinforced by my experiences with aging. Not to toot my own horn, but I've been aging well and have gotten more attractive the older I get (so far). My social skills have improved so much, I was painfully awkward and unable to successfully socialize as a young person. Holy fuck, I actually have real friends and relationships now, it's amazing. Yeah I got responsibilities, but I can actually do things I want to so long as I stay within the confines of those responsibilities, definitely not something I had as a kid either. And honestly, I'm a much better person, which I won't get into too much, but I was closer to being right wing in my younger days.
Sure, it'll stop feeling so great at some point, but I'm kinda past the point where most people start to say getting old sucks and you know what, I say no, it's pretty cool actually.
I miss being able to sport roughly, fall down and not have any lasting impact. I miss being able to live fully on impulse (at times) instead of spending all of my time and energy into staying alive and thus having to suppress my impulses constantly. I miss how amazed I got by every little adventure of exploration. I miss when breaking rules resulted in an adult berating you instead of getting beat up. I miss the excitement of learning new dimensions to life - first time stealing candy, first time winning an important(to me) prize, first romantic experience etc
I don’t hate being an adult and my childhood was not perfect but I do look very fondly to and miss certain parts of childhood. And I agree that there are many parts of adulthood that are great as well.
