Cold to the Touch

When you know her, she's more than the sum of her stats
Her schooling, her parents, and other such facts.
I think she is older than the sum of her years.
She's cautious in love and reasoned in fear.
Though she's not yet in her beauty's full flower
She already cultivates knowledge for power.
It would be wrong to say her heart's cooled,
But she doesn't let passion make her its fool.
To point out her youth is a truthful insult
To this shockingly-halfway-to-perfect adult,
Though when anybody tries to tell her as much
Her denial is frank, rather cold to the touch.
