Weekend writing prompt #180-Vault

Sammy cox has set a writing prompt this weekend, to use the word vault, in a piece of poetry or prose.

Here’s my attempt.
Locked in a vault
For all time
Never to be opened
Are her secrets
Secrets she can never reveal
For to reveal them
Would shatter her soul
She must keep them
Until her dying day
Never tell
Never say
Never reveal those long hidden secrets
