Like An Adult

I do not feel like an adult.

This morning this is the thought in my mind.  I want to expound the thought but it does not seem to translate from my head into words.  I told someone that I was a little bit childish.  I fear that was a lie.  I am more than a little childish.  I use this term “childish” not in a derogatory way but in a child likeness type way.

Can you have an old soul and be childish at the same time?  Are we always walking contradictions?
