Silent sentinels, they stand so tall,
Guardians of secrets, behind each wall.
Crafted with care, forged in steel,
A silent promise, a hidden seal.

They whisper softly, "Stay away,"
To those who wander, to those who stray.
Not for the thief, with cunning and guile,
But for the honest, with a trusting smile.

For locks are not to keep the wicked at bay,
Their clever hands find another way.
But to shield the truth from the pure of heart,
To keep them safe, to keep them apart.

A barrier strong, a silent plea,
"Do not enter, let it be."
For in the depths, where shadows play,
The honest soul must stay away.

So they stand, in the dark and light,
Silent sentinels, through day and night.
Not for the thief, with eyes so keen,
But for the honest, unseen, serene.
