An Invisible Reflection

A girl sits with her back to a mirror as she looks at her reflection.
It’s full of mistakes but shows undeniable perfection.
Staring back at her with eyes tightly closed.
She’s hidden away but completely exposed.
The face staring back appears different although they’re identical twins.
She’s innocent yet her eyes show all their sins.
The girl is blind and sees every detail.
Always successful, the mirror shows her every fail.
Doesn't believe anything, she’s completely gullible.
The reflection she sees is invisible.
