1.) The concept (or lack thereof) of money.
As a kid, you just thought everything was fantasy land and money was expendable. Then we grew into pre-teens and found out that that wasn't the case. And then we became full blown adults where money probably rules every aspect of our livelihoods. Childhood was so great....
2.) When Mommy and Daddy still paid our bills and made our appointments.
I really miss this part. Making doctor appointments is the hardest thing to do...and I really don't know why. It is literally just calling an office and making an appointment. Still, it will take me a good three months to actually call the office and get an appointment. (By the way, the dentists who automatically make your appointments for you are a literal gift from God.)
3.) Excitement over birthdays.
Whoo hoo. I'm getting older and now people expect me to be getting my life together. I miss when I was so excited to turn double digits, or to have birthday parties. Now, I'm excited for my birthday so that my parents will pay one of my bills that month. Same goes for Christmas and Easter. They just don't have the same magical feel anymore. Maybe it is because as an adult, you have to spend hundreds of dollars on gifts for other people just to get gifts for yourself. (Although, I know this is not the true meaning of Christmas, I'm just stating an opinion.)
4.) Energy...
As an adult, you look around at the little children running around like Energizer Bunnies and you're lucky if you can get through the day without a nap or 2 gallons of coffee. Then again, working multiple jobs may wear you down, so I may be biased. But, still, I would kill for the energy a little kid has.
5.) The world wasn't so scary.
I don't know if it is because the world is evolving in a negative way or because we are more aware of it at our age now than we were with kids, but...this world is scary. As a child, fairytales were real and nothing bad could happen, but as we got older ISIS became more and more real, shootings and terrorists attacks became a norm. Sometimes I wish I could go back just so I didn't feel the weight of the evil in this world on my shoulders sometimes. Where evil was the little girl on the playground who wouldn't let you play with her or the little boy who broke your favorite color crayon. If only evil and hate were as miniscule as that in adult life.
