What do you miss about being a kid?

I mean I'm sure there is a lot of things that we all miss about being a kid, for me, the thing I miss most was having absolutely no care in the world about anything and I REALLY miss that feeling of having no responsibility in the world in a world where I'm just hitting peak adulthood and the responsibilities are mounting. If only there was a way to time travel back to when I was a kid so I could enjoy it all over again.

What about you? What do you miss most about being a child?
