Liz's Letter (Poem?) to Yourself

At the start you were young,
You were small and bold
You had a spark on your tongue
And respect from the old
You were fire, strong and wild
Untamable with passion of a child

But you grew
(As is common in the land of the living)
And you settled with misgivings
In a supposed world of you's
You were air: you adapted
But truly you were a captive

And soon you grew more
Life became just a bore
Because your passions have dried
And your misgivings have died
Your fire is wet
Your air is like lead

Perhaps you are water, dynamic and fluid
But soon you will return to earth as a Druid
Like ashes to ashes and dust to dust
In the end you'll learn the end is a must
