A Fragile Truth

A heart of glass,
A feather's breath.
You'd think it would shatter,
With every small death.
Even though it is so soft,
So fragile a thing.
It can endure the sharpest,
The cruelest sting.

But it knows just one,
True, final sound.
A single break,
On solid ground.
And in that moment,
The walls collapse down.
The last defense,
In a quiet town.

What was whole is now,
A new, final line.
A strength of its own,
A new design.
It can't be hurt again,
It can't be broken twice.
It has paid its single, 

Final price. 

For a resilient heart,
And a heart of glass,
Share the same end,
When the final moment comes to pass.
Infact, even the most fragile heart,
Knows only a single fall.
It can be broken once,
A truth that is the same for all.
