Did u ever wondered how your life would like be as a teen of adult when u were a little kid?

I always fantasied about my teenhood and adulthood when I was a little kid in elementary school. Wondered what I would I'd do, what I'd look like (right now at age 26, I still look like I'm in middle school. This is definitely not what I was expecting when I was a kid), I was so eager to be a teen. (The whole thing that got me thinking what teen life would be when I was a kid was because I was always watching "Rugrats All Grown Up") But unfortunately, kids don't know what teen life feels like. They have no idea what difficulties and depression teens can have. And I sure didn't know. I was just a stupid little kid. How was I suppose to know? How was any of us suppose to know? Kids don't know what's coming to them as the grow up to teens and adults. Parents don't understand. And kids don't understand either. If we all had the ability to literally grow down, I sure would've been done that already
