Define Beautiful

Dearest Sydney,
Can you define beautiful?

To me,
Beautiful is when
Your eyes shine when you're happy.
Beautiful is when
Your hair blows back as you run.
Beautiful is
Your hips swaying back and forth
When you dance.
Beautiful is when
You laugh when I do something stupid.
Beautiful is
The expression on your face
When you're asleep.

What is your definition of beautiful?
It's the same as mine,
Isn't it?
I now you so well,
I know what you're thinking now.
I should, shouldn't I?
After all, you are me as I am you.
I'm just the voice inside your head.
Signed,
Your beloved Jake.
