Because I grew up.

Every time I realize that I'll never be seen as a little kid again, I wish that things were different.

Every time I realize that in the world of childhood, limits don't even exist, my heart breaks a little. Sometimes I wish that I were very young again. I wish to be innocent and carefree and ridiculously happy.

Then I think back to when I truly was young, and I wonder why my greatest wish then was to grow up. You see, growing up isn't everything it seems. Grown-ups don't always have the answers. Grown-ups are not unfailingly perfect. Grown-ups try and try and try, but they fail and they wish they were young again because then it wouldn't matter that they failed.

But when you're young, you don't know any of that. To be a grown-up is to be free of the rules and limitations that come with being a kid. Growing up is the ticket to freedom. Only when it's too late do you realize that you were better off where you once were.

But you can never go back.
