How To Be a Kid Again?

A lot of people, due to their life and family circumstances, etc., didn't have the chance to have a real childhood. They were hurt or forced to grow up too fast.

So here's my question to you:

How do you live your childhood over again? How can you be a kid as an adult?

We need ideas <3

To give you an idea of what I'm picturing, a couple of ideas I have are playing on a playground or drawing with chalk on the sidewalk. That kind of thing... Things people didn't do as a kid, that we can do now <3

What are your ideas? <3
