Cellophane

Prompt 9: You only thought you could trust her.

She is cellophane.
You thought you could trust her,
she would take your words, your sentiments,
wrap them carefully,
tuck them away,
keep them somewhere safe.
She would treat them with care.

She is cellophane,
completely transparent.
What you wanted nobody to see
is on full display,
trapped behind
an impermeable wall.
You cannot take it back.
