age is a number, i don't like math.

Hold up!
I still like swimming and sidewalk chalk and Adventure Time and going barefoot and doing dumb things. And I hate formalities and politics and wearing "professional dress."
And I also like deep theoretical thinking and good metaphors and driving a car. I hate Spaghetti O's and being treated like I'm not old enough.

I don't think the things you do make you a kid or too young or immature.
I also don't think the things you do make you grown up or mature or adult.
The things you do
just make you you.
And that is perfectly alright.
Better than alright, even.
I quite like you.

I don't expect you to try to be a kid or to try to be a grown up.
I just expect you to be you.
And I think you're pretty good at that.
